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.

God told me urine is sterile and if you drink it you become immune to COVID, which he created and I quote "to thin out the heard". He says he sick of all you bible thumpers passing judgement on your fellow man and doing it in his name. He says he gave you ignorant freaks a book of written instructions but you turned out to be too stupid to actually read it and follow the lessons instead you run around waving it in the air and using it as a weapon against your fellow human. He eagerly awaits your judgement day and keeps his pimp hand strong. So when your judgement comes he can reach back like a pimp and slap you like the dumb ignorant hoes you are.

So there is a separate orifice for eggs and for waste...they are separate, as the picture shows, but they are both under the sphincter flap that contracts to expell either an egg or a bolus of waste (as you said, both feces and the white urine excreament!) why did God design this like this? Efficiency! Same reason he put a ..."...playground next to a sewage plant! (ForgettingSara Marshall)" It was a funny movie! So don't bring God into do so only shows how much you need to know Him! God's Love, Mary

While it may be a “sterile” process, chickens tend to poop in their nests and the egg gets dropped there, thus, eggs are not sterile. They do have a protective coating so we don’t wash our eggs until we eat them.
