I have a small backyard flock and my EE has always been the head of flock. After a few months learning we had a ROO she began to get very mean to the other hens. We are not allowed roosters and he got loud so he was out. She then began not allowing ANYONE in the coop. Never had a issue with the broody and her newly hatched chicks. Although a few times she did try and roost in their coop for the night until I kicked her out. Now the past two days she has been EXTREMELY aggressive to the other hens, pullets and ESPECIALLY the broody! She gashed my broody's face I treated immediately of course. How do I get my SWEET EE back that used do sing and follow me around and not attack all in the flock!? I don't know what to do! I did place her in a kennel for a couple of nights since she would not allow any of the flock in the coop. She lets them in now only she attacks everyone all day long.
