We have a hutch with five hens and one rooster in it. We recently tried to introduce a new hen, but the rooster just went totally savage and attacked her and we had to remove her. Is there a proper way to do this? Most of the guides online seem to be for introducing another rooster. I wouldn't have thought our rooster would have a problem with another hen being around, but here we are. We are 100% sure she is a hen as she lays eggs. Thanks in advance!
