When hens were on the edge of extinction, roosters had a hard time finding a mate. Humans were on the verge of losing baby chicks…..and eggs to eat!

But luckily, ABO hormones appeared. The later generations of chickens were able to continue to multiply. Chickens laid eggs; eggs hatched into chickens.

The useless, skinny, little Omega chicken didn't receive a warm welcome for the reason that it was hard for him to get pregnant. Until one day, when he met a fat and blind rooster.

Afterwards, they became the world's most handsome Alpha chicken and the world's most fertile Omega chicken.
