Can chicks end up inbred if the rooster came out of the same clutch that the hens came out of? I bought pullets at Rural King and one ended up being a rooster but they were the same age, and when I hatched chicks, some of them had problems. One is missing a wing and on it's foot, one toe is stuck to another toe. One has spraddle leg. Is that why, or can chickens even be inbred?
