It's been proven scientifically that if a female doesn't have a male in order to procreate, the female will generate the proper male hormones to induce procreation without the actual presense of a mail, so.......... chicken! Sounds delicious!!

What about the rooster???

it was bird prostitution
one kind of bird did it with another kind of bird and well one of them got pregnant and that was the egg of the chicken
inner bird species sexual encounters

neither-the rooster came first

The earliest Cave Dwellers were called "Crow Magna"
and when a group of them discovered perfectly oval stones in a creek bed they took them home and placed them symbolically on a rock ledge. They then covered their caves with ornate images of these stones, holding them in reverence as deities brought from the bowels of the earth. One day a bolt of lightning struck the mountain above their cave and the stones sprung to life. Most of the full grown chickens flew the coupe (creating the first really bad car/cave joke) leaving only broken shells behind, along with a few charred feathers and three dead birds.

On this day the first chickens were produced. The three which did not survive were charred. Tempted by the smell and very tired of roast Brontosaurus three of these earliest humans ate the birds. The first of the men was known for his trait of sleeping on beds of sand. They called him the sandman. Later generations would be called Saunders which would eventually evolve into Colonel Harlan Saunders, creator of KFC.

The second man was a swamp hunter with a penchant for wrestling Dinogaters and snakes. He received the most heavily toasted bird and passed the recipe along his geneological lines until it was finally made famous by a group of Cajuns living in Louisianna. Uniquely they called it "Blackened Chicken"

The third man died by choking on a chicken bone which caught in his throat. Being unfamiliar with the term "chicken" The cave dwellers called the escaped birds "crows", named after some small reptilian birds they often noticed in the black swamps and deathly feared; hence eating crow became a popular term denoting something very insidious. In later years "eating crow" would refer to apologetic behavior. Intimately woven into the DNA of most men was some message going all the way back to the Stone age which shouted "Never apologize for anything or a bone will stick in your throat and you will die" Most cave women of that earliest era saw the humor in the situation and laughed, calling the men "Boneheads" later they shortened the name to "Boners" creating the first reference to men as the most primal phallic symbol. Not knowing about human physiology they believed that men were directed by their genetalia. How silly is that???
