Biddy had started attacking all of my other hens, and even my large Plymouth-Barred Rock rooster. My chickens are missing feathers, and due to the cold weather, I thought it best to put her in a temporary pen next to my other chicken to let the others get their feathers back. (Lady, the other isolated chicken, is bow-legged, and is attacked constantly by all the other chickens.) Somehow, she got in with Lady, and I when I found them in the evening, they were happily cuddled up together under Lady's heat lamp. I fed them, and Biddy stood guard like a rooster while Lady ate, and started "growling" at me when I came to close. I think Lady likes the company, and I honestly think Biddy would protect Lady should something happen. Should I leave them together, and just let Biddy think she is a rooster?
