I have only ever had one rooster with my girls. Well, one of my cochin chicks turned out to be a rooster and he's a mean little devil. He is constantly trying to mate with my black polish and now she's lost a big patch of feathers on each side of her neck and the lower part of her crest. Can this be stopped or should I just rehome him? I had no problems with my flock until he started in with this.
