I have my two 20 week old roosters separated in their own pen because they almost killed one of my hens a couple of weeks ago. They were chasing and aggressively mating her and tore the back of her head and neck open. I was planning on butchering them this weekend but now I'm not sure. Thursday two dogs dug a hole under the fence and got into my yard. They managed to kill one of the hens before my mom (who's 86) made it outside and chased them out of the yard with a stick. The reaction of the roosters was telling. She told me both where yelling their heads off before she got out there. However the creel one, who is the dominant rooster, hid in their coop while the white rooster was going berserk attacking the side of their pen trying to get at the dogs. Do you think that if I keep the white one he will calm down toward the hens once he is the only rooster? I'd love to have a protective rooster. Neither rooster is aggressive to people.
