Was wondering if anyone has any suggestions. I have three hens. Chick-Chick, Lucy & Ethel. All have been together for a few years. Within the last month Lucy has been picking on Chick-Chick something awful. When she does it, Ethel will jump in and beat pick on Chick-chick as well. The poor thing is always trying to avoid them. I've caught them cornering her, standing on her and pecking her. When that happens I separate for awhile, but I'm not always home. Any suggestions? I'd hate to have to build another coop for just 1 chicken, but I'm afraid they could kill her. Help, please!
