"A rooster often employs a type of foreplay by prancing around the hen and clucking before mounting her. The transfer of sperm happens quickly without the penetration normal in mammal mating. The cloaca, or vent, of the male and female touch and sperm are exchanged.

It’s called a “cloacal kiss” and requires a bit of avian gymnastics for both birds to position themselves so their cloacas meet.

Just what is a cloaca? Unlike humans and most mammals, a female chicken has but one rear orifice with three functions. It is where feces and eggs exit her body and sperm enter. The rooster’s cloaca has only two functions. One is to pass feces. The other is to transfer sperm to a hen."

"Things are awkward in the avian locker room. While waterfowl like ducks can proudly strut their stuff, the rooster—that emblem of virility—probably keeps a towel wrapped firmly around his waist. Unlike the rooster’s well-endowed aquatic counterparts, he has a ridiculously small penis.

Given the chicken’s agricultural importance, scientists long knew that, like 97% of bird species, roosters didn’t have a significant penis—at least, not one large enough to deliver semen deep inside a female’s reproductive tract. "
