We have a 13 week old Blue Ameracauna rooster, that we thought was a hen. He is very sweet to us and will tolerate being held and petted. However, he started attacking 1 of our hens about 3 weeks ago, very bloody. We isolated him for about 1 week and then tried to re-integrate. The next day he had attacked her again, bloody and went back to chicken jail. Yesterday we tried to let them forage together supervised and he immediately bit her comb and wouldn't let go until we pulled her away from him. He quickly then attacked another hen's comb and is now back in chicken jail. None of our girls are sick that we can tell. We are looking for a new home for him, any last ditch advice? Anyone ever rehabilitate successfully a rooster that is an aggressor instead of protector of his ladies? Thanks!
