Hello! Really worried about my chickens. I have 5 total chickens. The oldest one (by 4 months) who has been the "head" chicken as recently been targeted by my other chickens. She does not appear to be sick, bleeding etc. She has been escaping the chicken run b/c the are outright attacking her. I've never had issues with them until now. They are all close to a year old. Can someone please tell me what could be the possible issues? If she seemed sick or hurt I could totally understand. I let them free range for about 4 hours a day so I don't think they are stir crazy. Any suggestions are welcomed as "Sweetie" is my last Easter Egger and my favorite chicken. We are totally bummed right now.
