I have 7 chickens total, very mild manner breeds. They free range the yard and surrounding areas most days, and have a beautiful coop, and all organic feed. We love our chickens! However the dynamics have just recently changed. Our wonderful Wellsummer Rooster was found dead, and two chicks were born all within one week. The Broody hen is a wonderful mother, she is separated from the rest of the hens on most days, due to our house cat. But will mix sometimes(when cat is locked up) with the other hens and her two chicks. everything has been going smooth for the last 3 weeks, and then all of a sudden, one of the Wellsummer hens started attacking the Broody hen(black Australop) through the wire fencing. We chased the wellummer away, and all seemed calm. Until last night, I heard screaming and the wire fencing that is separating them shaking. All their feathers were up and they were flying together like roosters fighting, their faces bleeding, and this all through the wire fence! I'm not sure what to do? It seems to be coming from the wellsummer, she seems to come after the australop? I don't now if this matters, but the chicks are the wellsummers. But the eggs were put under the broody australop. Any advice? Thanks!!
