Do Chickens Have Vaginas? What Hole Do Eggs Come Out?

I've always wondered - do chickens have vaginas, and what hole does an egg comes out of? Is it the same hole as their poop? How does this all work? Chicken eggs may be one of the pregnancy superfoods, but the reproductive and digestive design of a chicken seems super-gross.

Years ago, I was astonished to discover that a chicken's egg comes out of the same hole, called the vent, as a chicken's poop. Originally, I thought that if a chicken's egg comes out of the same hole as its poop, that was a seriously bad design. Chicken poop is gross and smells like rotten cigarette butts! But chickens DO Lay eggs out of their anus! Bear with me, because it's not as bad as you think.

Do Chicken Eggs and Chicken Poop Come Out The Same Hole?

The egg, poop, and urine exit out of the same hole, also known as the vent, as you can see in the photos. But the cloaca is the real hero in this story.

Chickens do not have vaginas, but some people call the end of their reproductive tract, right before it enters the cloaca, a vagina.

The Cloaca

When an egg comes out, the chicken's cloaca is turned inside out so that the egg does not come in contact with the intestines or any fecal matter. I'm happy to report that egg laying is not a bad design! Chicken poop does not come in contact with eggs, unless a chicken decides to walk in it and then put her talons on her eggs. Here's a link for the whole story or check out the video down below to see it in action.

Chickens lay eggs and poop out of the same hole, called the vent. However, because of the cloaca, chicken eggs and chicken poop/pee never mix because the chicken's cloaca turns inside out when an egg is laid. This makes it so an egg and chicken poop never touch.

Do Chickens Have Vaginas?

Chickens do not have vaginas, or what we think of as a vagina. Chickens have only one exit hole called a vent, which is the outermost part of the cloaca. The cloaca is a chamber that the reproductive, digestive, and urinary systems all connect to. This means that eggs and waste all pass through the same opening, but without touching. (Some people call the last bit of a chicken's reproductive tract a vagina, the part right before it enters the cloaca.)

In the cloaca of a female chicken, sperm from a rooster is deposited during mating. The egg then forms in the hen's ovary and travels down the oviduct where it is fertilized by the sperm before being laid. So while chickens may not have vaginas like mammals do, they have their own unique reproductive system that allows them to reproduce and lay eggs.

Some people call the last bit of a chicken's reproductive tract a vagina, the part right before it enters the cloaca. Both eggs and chicken waste exit through the same hole, the vent, but never touch because of the cloaca.

Do Chickens Pee?

Do chickens pee? Chickens do not pee in the same way that humans or other mammals do. Instead, chickens have a chamber called a cloaca, which serves as the meeting place for waste and urine.

When chickens eat food, it passes through their digestive system and is broken down into nutrients that can be used by their body. The waste products from this process, both solid feces and liquid urine, are mixed in the cloaca, and exited through the vent.

The urine produced by chickens is mixed with their feces, forming a substance called uric acid. Uric acid is a white paste-like substance that is expelled along with the solid waste from the cloaca. (Chicken owners know exactly what I'm talking about here!)

Because of this unique system, you won't see chickens peeing like other animals. Instead, they release both solid and liquid waste together when they "go to the bathroom".

Side note: It's important to keep your chicken coop clean to prevent buildup of waste material, as excess ammonia from uric acid can be harmful to chickens' respiratory systems. Regularly cleaning and maintaining proper ventilation in your coop will help ensure your flock stays healthy and happy.

    1. I am just so glad it doesn't come in contact with the chickens beetle matter but damn it really does come out of the butt? Lmao

      1. Great info! Now if I could get the chicken diaper on my new pet chicken so she could walk around the house with me!

    2. You are an idiot lady. God knows what he is doing when it comes to laying an egg and taking a dump! It's completely sanitary process.

      1. That's not a very "Godly" response however I was thinking the same thing about everything being designed perfectly and harmoniously by our most high Creator!!!

        1. If god was such a great designer please explain cancer, earthquakes and extra chromosomes that causes Down’s syndrome...

          1. The world was perfect before the fall of Man. Because Man sinned and brought evil into the world, the fault was our own. God was merciful enough to give us free choice and we ruined it.

          2. God didn't create cancer man did . Like sodium benzoate Mei for that caramel coloring for pop sodium benzoate is a preservative when you mix that with vitamin C it causes cancer. Man causes cancer not God. Keep your body alkaline keep your thyroid functioning correctly we should be fine. Keeping the body alkaline is true calcium but when you take calcium you have to make sure you take magnesium so it does it calcify and your arteries. So don't blame God it's man doing it

          3. Man caused cancer. Extra chromosomes is a mutation in the genetic make up. And natural disasters are a sign. God created the world and man. We have bad with the good. There was paradise in the beginning but mankind ruined it.

          4. Sin was born on the garden when Ever and Adam sinned, but even before that Lucifer sinned, God is a loving God, just, human nature is sinful, God allows things to happen we don't always know why, but we have to trust him. He has already for seen the future of us all.
            In the Bible, he allowed things to happen and then performed miracles so people would believe that Jesus was who they said he was.
            As a Cancer survivor, dought always comes to mind, but you have to trust in his plan for us.
            Remember Satan is real and also has power.

          5. Most diseases are outputs of human innovation responses but God knew we humans are not as intelligent as God so God provided a cure for all even when we mess up. Natural disasters are also causes if oil being removed from beliw earth layers and i jecting chemicals into earth.....in irder to balance these changes the earth vents off heat or plates move bringing volcanos and earthquake.....have u ever imagined what would happen if God did nit design rain to fall as showers or snow to flaa as flakes? God is oerfect in everything that why God is called HOLY.......qhat we mess up Hod rectifies patiently and in much kindness....blame the people for their greed in misusing resoyrce not GOD

          6. I was strangled by my mother's down syndromed cousin. They are quite strong, smiling drooling faces as I gasped for air. You're right, how could the creator have such a sick sense of humor?

          7. How dare you blame God for all of those horrible things that happen he didnt make it happen!!! I say again HOW DARE YOU!!!!

      2. If god knew what he was doing, he would've given the chicken a separate channel for the egg instead of sharing a vent with the feces

        1. Hmmm why does air and food and water go In one preface (mouth ) but then through Gods design and purpose it actually byinvoluntary function separates the distinction of food wa tr er to the intestines stomach and air to the lungs. So we are like a chicken but the chicken has a dual purpose butt and we have a multi purpose mouth

      3. First off your religion is a sham. It is a very new religion compared to others not to mention it took most of it's stuff from other religions what's left is fantasy. Secondly your a hypocrite and a disgrace to your religion's foundation.

        1. What's religion is documented as being older than the bible Smart Alec?
          You know, one day you will bow before Him and say that he Lord of All. You may say , No WAY, or curse me out now, but the Bible says so. Soften your heart and stop being hateful and miserable to yourself and to others.

          What's the point in tearing others down? I don't criticize other religions, I just promote mine, one of the One True God who created all. You don't win hate over with hate, you win it with love.

          "Therefore encourage one another and build each other up, just as in fact you are doing." Thessalonians 5:11

          1. The bible is the worlds biggest fairy tale. May be based on a few truths that happened in the world. But come on, a God. Cannot ever be proven. And why on earth should I have to kneel.

          2. If the bible is the worlds biggest fairy tale then why do you feel it even necessary to comment that God cannot ever be proven? If He is fake then aren't you just wasting your energy?
            If you have no interest in where you end up the moment you die then why does God matter enough that you have to try and disprove His existence?
            Once you've actually had an encounter of God and realize you can't just chalk it up to coincidence, the world and the way you view it takes on a whole perspective.

          3. So you want us to lie to you? I have news for you God is no different than Santa Claus the easter bunny tooth ferry unicorns and leprechauns . Religion is a man made concept you do know mythology was the predecessor to modern day religion? There is no God when you die you're just dead. Sorry to rain on your fantasy but look at it this way at least you don't have to worry about hell cuz it don't exist either.!

          4. Wow this egg convo really spun out quick. What a moron. You jesus freaks are the worst. If there is a God (there isn't) it certainly doesn't want humans pretending to know what he wants so they can, control the population by fear, collect money, and judge fellow humans like you religious sheep like enjoy to do so much. God especially doesn't want to abuse children and protect child molesters like some religions have done or persecution and murder of people who dont agree like some religions do. Obviously i know there is no reasoning with you fanatics but the stupidity displayed even bringing religion into this subject frustrated me enough to comment

      4. My grandma had chickens and I can tell you that most of eggs a covered with ugly poop. Do you know who else eat eggs?........ a snake. Lol. I would also appreciate if milk was labeled “animal breast milk “. Enjoy consuming products made out of what comes out of animals breasts and ass. 🙂

          1. It can and does happen! I own chickens and of course its never happened with mine. BUT if they have worms that is one of the main signs of worms is poop on the eggs. So MAYBE you should google it!

      5. You are an idiot. Believing in an invisible man who lives in the sky, watching everything you do 24/7. No need to be an asshole.

      6. God is imaginary. Made up by prescientific humans.
        This false belief has nothing to do with hens laying eggs.

    3. Who ate the 1st egg. One cave man says to another "hey, let's eat that white thing that came out of that chickens Ass ".

      1. Many predators eat eggs.
        They don't think about where it came from, they just know those are unhatched baby meals ready for the eating.

        I imagine the first humans to eat it be "hungry, when egg hatch? Need baby chicken eaten!"
        "No wait lazy chicken! We eat now!"

    1. No kidding I have an egg bound chicken for 5 days now. I have been soaking her in warm ebon salts and lubing her no egg yet does anyone have a suggestion

  1. Thanks that is really interesting my friend Imani went carzy when she saw the picture of the 2 tubes. I am sure that people have found this as facinating as I have.

        1. Intelligent design? If thats not a contradiction in terms I don't know what is. Because if you believe that you're clearly not

          1. Mr. Reality, you are obviously not well aware of science. The world cannot exist according to science, the “Big Bang” is a fairy tale, as the second law of thermodynamics requires all things to tend to lowest energy states... Without adding energy to the universe, it is against this LAW of thermodynamics. Laws in science cannot be broken, or they are not laws. So if you are truly a science believing “realist” then for your soul’s sake, figure out how the universe might possibly be here without adding energy to the system! Next, consider evolution. Just like the universe, species (or anything else in the natural world) devolves to a state of lowest energy. Things don’t improve without adding energy...ever. Can you imagine any system where it gets better when left to wind down? Nope. So “intelligent design” means God put energy into the system to cause changes, positive evolving of traits, and boom...he had a great time creating the world this way. So his name means “The Great I AM” the only being in the universe that exists on His own. He uses his energy to overcome entropy and create humans out of the blankness of space...imagine all of this happening accidentally from the blackness of a vacuum...without energy. Next tell me in scientific terms how that is possible. Smart/logical/determined people are willing to apply their abilities to understand. Do this and take part in the real point of the universe...God is creating us, enabling us, thru Christ and our gifts, to become part of his family for eternity...he won’t be alone anymore. We won’t be puppets like angels, we will be those who freely chose...and now part of the Great I Am! Please consider this. I’m a scientist and have spent a lot of time researching just so folks like me, who require logic, to see that there MUST be a God, or we wouldn’t be here. It is up to you to find that Christ is the only path to that solution! May God Bless You.

      1. Evolution is SO over for those who have a brain. We knew it was a bogus theory to hide the truth. But, those who follow ignorance still believe in the joke theory of evolution.

        1. BAHAHAHA! What's intelligent about disregarding libraries worth of evidence supporting evolution and ignoring the absolute dearth of any evidence that there is an alternative method?

          Just because God made the universe doesn't mean he didn't set it into order with these processes in play. What's the point of making something static and boring like the Bibles take on zoology? Obviously, this is a reality in which novelty is paramount. Random chance within a progressively ordered system allows for the greatest amount of novelty. Evolution is therefore completely in line with a creator's design.

          P.S. Dogs = human guided evolution. You can see how breeding for certain traits diversified wolves. That's just using the mechanisms nature has given life to explore different avenues of form based on the needs of the environment. Environments are always changing, so why would there be a static biological system? Woolly Mammoths needed fur in order to survive the ice ages. Most of their stomping grounds are now too warm to sustain them, if they had survived. They either failed to adapt entirely or some of them went on to become non-woolly elephants. That's evolution. Anything else is wishful, delusional, thinking. GL with that 😛

          1. Are you idiots seriously turning this into a commentary about religion? But no, evolution is still very widely excepted by people who actually graduated unlike you.

          2. God made nothing, he is a fairy tale much like Cinderella.
            Do you believe in talking big bad wolves? If not then you shouldn't believe in a god.

          3. Your thought on evolution are about as probable as disassembling a 747 airplane putting it into a giant box shaking it throwing into the air and praying it will evole into a functional airplane.Man has finite knowledge of the magnitude of the solar system and all the many universes that are kept in perfect harmony.and you want tell me im dumb and there is no God .Study the anatomy and complexity of the human body Its far more complex than a 747 airplane. PLEASE go back to school and learn about the complexity of the human eye and you will soon see ( pun intented) there is a supreme creator.I call Him God . Ps.i own an original set of Darwins books on evolution perhaps you should read sometime.... they will surprise you it's not what you think

      1. Ichor states..

        Are you idiots seriously turning this into a commentary about religion? But no, evolution is still very widely excepted by people who actually graduated unlike you.

        Ummm. If you had graduated from anywhere other than grade school you would have known the word is "accepted"... Not excepted.

        1. I learned, in grade school, how to punctuate, structure a sentence, and the proper use of capitalization. If you had gone to grade school, you would have learned that the proper structure of your sentence would be:

          If you had graduated(,) from anywhere other than grade school(,) you would have known (that) the word is "accepted"...(n)ot "excepted.

          Before attempting to remove the spec from another's eye, remove the plank from your own eye.

        2. CJC: Thank you. It’s amazing how many smart, brilliant people can’t spell or use correct punctuation.

  2. Yes, eggs come out of the anus. So far as being "sterile" that is untrue. Anyone who has been there to see the eggs after they come out knows they are often covered with blood and feces.

      1. hi Jo.
        please advise on how many chickens you have and must one check daily for eggs? I have read that only at 20 weeks do chickens deliver on eggs. doea it deepen on the food one gives them and love and attention and sunlight? how does one make sure your chickens are happy?

        1. The hens need to develop (about 20 weeks) before they lay. Yes, they need good food, water, sunshine, dust baths and some space to free range. Oh...and some love.

      2. Sometimes my chicken's eggs are clean and sometimes they have some brown sticky stiff on them. I have been told not to wash them before you use them or they will rot quicker. They have a covering on the egg when they are hatched that protects the egg from rotting easier. The seal on the egg should only be washed off before they are cooked. We soak them in water then rinse the eggs, put them on paper towels and wash our hand really well before we boil or crack the egg!

    1. THANK YOU! Why would anyone think an egg is sterile?

      There are diseases that are spread to the baby chick from the mum - this has to be transmitted VIA THE EGG = not sterile.

      There are diseases that are spread to humans from eggs = not sterile (Salmonella anyone? Hence the whole 'don't eat raw cookie dough' thing).

      While I"m here let me dispel another commonly mixed up fact regarding what is sterile and what is not: URINE IS NOT STERILE. If you've ever heard that it is, you've heard wrong.

      Thanks, k bye

      1. In saying that though ayriel is a bit insane. It's meant to be sterile, but a chicken doesn't clean its anis so it gets the poop from the opening sometimes...not the insides...same with urine, it only becomes unsterile when it touches the outer parts of the body. If you are healthy you won't grow anything from urine...it's only if you add the germs...like uti

        So yes eggs are meant
        To be sterile, and so is urine!

      2. Eggs are sterile. Salmonella is pretty much non-existant in backyard chicken land. The final coating the hen puts on the shell is a thin film called the "bloom"; its job is to keep the egg protected from bacteria and other pathogens while also allowing the egg to "breathe". Salmonella only gets in once this bloom is washed off (take a wild guess what they do to commercial eggs - yup, they wash them!) which is why no chicken owner in their right mind washes an egg until right before cracking it into the pan!

    2. Wow! That is so untrue!! My hens lay one eggs a day each. I have never ever in two years seen blood or shit! I guess it's their living conditions!!! My 9 chickens are free range and beautiful and very healthy... SMH if you own hens you are doing a terrible job with them!

  3. In that drawing, it looks like anything in the last part of the intestine will be squeezed out ahead of the egg. Then the egg plops right on top of it.

    I've collected eggs. Unlike Chuck, I never saw blood, but there definitely have been suspicious substances.

  4. That is so awesome! Like you I knew nothing! Started with 3 poets and this year got Brave and got sixteen chicks now I got even braver and got two ducks and this just crossed my mind thank you so much for your expert advice

  5. My little friends and I figured this egg thing out while we were in the first grade. My only comment " POOR CHICKENS " !

  6. I'm thinking of getting chickens myself... for the egg purpose
    I needed to know this answer. I am also looking on where and how to get started with a chicken coop and nests for them. what to feed them ect. if anyone can assist I would greatly appreciate it. I believe that the eggs from free chicken are way better. yes I will have a closed coop but they will be walking around in the fully enclosed garden. Are chickens noisy? no I do not want any rooster. just the chickens. please advise.

    1. Go to my pet chicken website, they have pretty much all needed information regarding food and what ages to change them, diseases, etc. I built my own coop and run without a plan, it's not really that hard, but is tiring. I pretty much just use wood chips as bedding in the coop, my hens have started laying eggs, so I changed their food to layer and basically followed guidelines from the website, all is well so far. I only have 4 , 1 rooster and 3 hens. I started with 6 chicks, and turned out 3 were roosters, I gave 2 of the roosters away. I am currently trying my hand at incubating 7 eggs, in hopes of getting 2 or 3 more hens, and then I'm done, really just want them as pets. I have silkies, and their not really known to be huge egg layers. And they lay very small eggs. With that being said, they're pretty new at laying eggs, and I usually find 1 a day, sometimes 2 . They haven't figured out how to use any of the 6 nesting boxes yet, they just plop their eggs out wherever they are. I am working on teaching them to use the boxes though. It took them a couple weeks to figure out how to use the ramp to get in their coop. And a few months to actually get on any of the perches in the coop, but they usually sleep in a big pile in the corner. They are interesting, cute, and fun. I love mine. I am trying different snacks on them, they love meal worms, cracked corn. I've tried apples, grapes, raisins, salad, watermelon, and they love salad and handfuls of grass, the others they haven't taken to yet. Well grapes were eaten once, but left on plate another time. I hope you success in your adventures in chicken raising if you decide to go that route. I am enjoying mine so far.

      1. God gets the Blame or credit for everything in life! My My People cant just sit and accept the wonders of the moment and Glory that was created be it by God Almighty or by other Matters or Creation..Earthquakes a Matter of Instance that Occur when the Plates of the Earth Crust move, just as a door jams when the House shifts accordingly with Wind and Rainfall which enact the movement of the structure accordingly! Birth Defects, well they happen as a fluke its Not Gods will nor is it his creation or Destruction, its just a matter of Instance! as for Death, well that Life so to speak, we cant go on forever as the Earth would become Over populated and too crowded for each man to survive anyway..Death is a wonderment of Life, we celebrate a Birth and in turn must learn to celebrate a Death or the achievements done in that life be it for a moment or many years, a Life came and went!..Man must accept his or her own Mistakes or Credits if they had an impact on the wrongs or Rights that happened in Life...We each learn something or accept something new each day of our Lives and therefore must appreciate its Complexities of and to then Further on to the next day and do the same or similar again.. A nut is a nut that falls from the tree we pick it up and eat what the nut contains..same instance with an egg..Food is food regardless.

  7. No chicken/hens lay the eggs out of their vagina just because we all can't see the vulva area does not mean they don't have one cause they all do I'll explain theirs is like a tube with 2 holes on each side a little ways inside the tube/vent.

    What I don't know is which side is the vagina on the left or the right up in the tube I just wonder is all just like everyone else.

    When mine lay any eggs they all come out clean and warm it may have one dot of poop but your gonna want to wash them off anyhow so that doesn't really matter mine has never came out dirty with blood or lots of poop on the eggs I think the chickens that lay dirty eggs maybe more neglected and untaken care of ones that have to walk around in their own poop and pee. I believe if a person can't take care of a few chickens by cleaning after them then those type of people don't need any pets chicken flue start when people have over two hens they get illnesses from having to many in a small area plus an unclean area also if you keep the area where they are at clean then you have clean chicks.

    I have seen dirty chicken barns and dusty shit everywhere a few dead chickens why because the old farm guy has to many chickens in one spot i told the guy you need to clean that shit up man. i think how that guy keeps his is how chicken sicknesses start up that's what I believe.
