Hello!! For some reason we have a white bantam hen who if we put any roosters in with her she will automatically kill them? She has killed 2 of our most expensive roosters when we put them in with her(obviously one at a time) and she managed to get in the pin next to her and killed one of our original hens! We had put a rooster in with her one time and we of course watched and she like snapped his neck quicker than we could even reach in her cage to get the rooster out. She is NOT aggressive towards people i just dont understand why she is killing roosters. Any ideas why a hen would kill the roosters? Its usually vice versa?
