Like penis in mammals, this is seen for the identification of the male chickens but it does exhibit its function in the same way as the penis. The papilla is the organ through which the sperms exit. The roosters do not have a penis because when they were an incubated egg, a cell death protein named Bmp4 covered their incipient penis and stopped its development, leaving it as a small bump or nub.
The eggs that will become roosters start developing penis but the development stops later during the embryonic development because of Bmp4. The roosters play a necessary role in the reproduction of young ones as the roosters release the sperms which fertilize the egg. If a hen does not receive sperm from a rooster, the eggs laid by that hen will be incapable of developing chicks.
A rooster is supposed to produce 35, sperms each second of its life. For a hen to lay hatchable eggs, rooster and its healthy sperms are vital necessities. The roosters first exhibit mating behavior like a mating dance or encircling the hen with one wing dropped to the ground to impress the hen for mating. The hen is likely to flatten its back and crouch for the rooster and stay still until the rooster mounts the hen.
He then ejaculates, deposits the sperms, and hops off. Once the mating takes place, the rooster may show victory dance while the hens simply straighten her wings by flapping them, and walk away.
The mating process takes only a few seconds. The sperms enter the oviduct from the cloaca and it is where the actual meeting of the ova and sperm occurs, known as fertilization. The sperms get stored in the oviduct so that the eggs can get fertile for two-three weeks and even longer. There really is evil in this world with so much abuse towards innocent animals, it only reflects what kind of person they are. You are commenting using your WordPress.

October 14, April 3, Just wow! Nature is fascinating as is sex! Elizabeth Burrow. April 6, November 28, May 12, What is the little white thing in the egg? Bitchin' Chickens. A rooster does have an organ called the papilla that is inside of the cloaca. However, while this papilla can be used to identify a male chicken, it does not function in the exact same manner as the penis for male mammals.
In order to really establish the concept that chickens are not mammals, please consider how their young develop. A chicken, however, does not carry its offspring internally. Also, in order for the young to obtain the heat that is so crucial for them, a mother hen must sit on the nest for long periods of time without moving. Another notable difference between mammals and chickens, is that a mother hen will periodically roll the egg — prompting the young to move around inside of the shell.
Speaking of food, a female mammal will supply her young with nourishment. A mother hen can not do this, as the young are no longer a part of her body. Mating behavior varies from species to species, with some of the more intelligent species having the more in-depth courtships.
Roosters, however, really only fall into one of two categories when it comes to courtship; Good Behavior or Bad Behavior. The reasoning for this is in their instincts. This is why, roosters kept together, will quite often fight and kill each other — even if they were raised together as siblings. Some will be ready earlier than others. But regardless of the breed, roosters tend to exhibit dominating traits long before the hens are ready.
