I decided to set an egg from another breed to my silky hen when it was broody. The chick hatched and everything was okay. Suddenly the hen started feather pecking her own baby chick. Is that normal? I separated the chick from the hen to avoid her killing the chick. At first she went crazy, but she didn't stop pecking it. The chick is changing the feathers now. Is the hen helping on the molding?
