One of my buff orpingtons went through a terrible molt this winter, and now appears very pale in her comb and wattle. She is eating well and her activity level is fine, however, she has had a change in her personality-- she was the dominant hen in my flock of 4, but is now more stand off-ish of the rest. She hasn't yet started to lay again. I have fed them all the same-- feed supplimented with extra protein and fat sources for the winter cold. I have started adding food grade DE in case it might be worms. Any advice is appreciated.
