I am so frustrated with my 3 barred rocks!!! My neighbor gave me 3 older chickens that he couldn't care for. My younger 3 barred rocks ATTACKED one of them today. She jumped on her back and started pulling feathers off. I hate to say this but I HATE THESE BARRED ROCKS!!!! I don't know what to do for them. I am on the verge of having them for dinner if they don't shape up now. Please help!!!
