names of HYVs of a hen

Hen, rooster, roo, capon, chicks, peeps: You probably know the terms "hen" and "rooster," which refer to female chickens and male chickens respectively. "Roo" is just short for "rooster," and "capon" refers to a neutered rooster. What you may not know is that we don't normally refer to young chickens or chicks by those terms. A baby chick is not a hen or a rooster. "Hen" and "rooster" are terms used to refer to adult chickens only. By contrast, baby chickens of either sex are called "chicks," but can also be called "peeps." Why aren't there different terms for female baby chicks and male baby chicks? Probably because historically, it was many weeks before it was possible to tell them apart. The Western world didn't know how to tell male chicks from female chicks until the 1930s, when we learned about it from the Japanese.

Chicken, rooster: Sometimes newbies get confused and think that "chicken" means female, and "rooster" means male. So we sometimes hear people say things like, "I have ten chickens and two roosters." What they mean is that they have a total of 12 birds: ten hens
