My buff brahma has had a bald butt for months now. Ive tried everything that i can think of. Higher protein food, meal worms, checked for mites, sprayed with bluekote, changed food to feather fixer, watched for picking etc. Her feathers just wont grow back! We had a blizzard last week and now her butt is really red but she acts fine, eats, scavenges, digs, lays eggs, follows me around and seems healthy. What else can i do?
