I think my Black Copper roo is breeding my pullets to death...My five month old BC roo, (Wade Jeane line) has started wanting to breed and crow alot over the last 3 weeks. He is chasing any pullet he can corner. Problem is, he is HUGE (about 6 pounds already), and over twice the size of the poor pullets he has been chasing. I found one hurt beyond help and I thought she was sick. Upon further examination, her breastbone was broken. I found another one dead and another one with a hurt leg, but it is fine now. I did not realize at first what was going on, until I caught him in the act. He simply won't get off the pullet after finishing his business. I don't believe it is intentional, but that he hasn't realized he is hurting them. The ones he has hurt are the smaller ones, the older pullets are fine. Has anyone else ever had this happen, and is it common for BC roos to get this big and aggressive this fast. My other marans roos are not this big, just this one. And he is an absolutely beautiful bird. Will take pics later today of him.
