I am new to raising chickens. Today two of my hens started fighting. All my chickens are the same age and are basicly muts. So mixed up it is hard to tell what they are. My kids wanted chickens and there was only one place localy that had them so we got a mix of chicks all the same age just about 6 months. We have 9. Only one crows but I suspect there are 3 males. But the males are not the agressors. At first I did not worry because I did not think they could do any dammage. The kids were playing in the yard with the chicken they thought was being picked on all day. But tonight we went out to dinner and by the time we got back an hour and a half later the chicken was laying by the door bleeding with all his head feathers plucked out. I have since moved the chicken to the basement and the one who was doing the pecking has been put back into the smaller pen we used when they were chicks (until we finished the big pen.) So my question is, is this natural, do I get rid of the agressor, the weaker (he does not seem to attack the other chickens) OR Both, Or is this a weak chicken, strong chicken thing. The other chicken was also pecked also but much less so, So I just guessed he was just fighting back. For now I will just keep them separated but I do not think this is a kind thing to do because the chick cage is just far too small for a chicken to live in. And Even with a heat light I do not think a singular chicken can survive the Winter in GA. I had chicken for a year back in CA about 5 years ago before we moved, but I never had fighting among the chickens and if we did it would have been a simple matter of caging them away from the house, as I lived in the desert. But with the temperature here I am not sure what to do. Any ideas? PLEASE HELP ME MY KIDS ARE SO WORRIED ABOUT THERE DEAR CHICKEN "SHADOW"
