I have 7 Rhode Island Reds and one of them keeps pecking herself! I don't know what to do! She is eating and drinking just fine and she runs around with the other chickens just fine too. I have been feeding her twice a day (2 cups of layer and 1 cup of B.O.S.S morning and night.) I think she is getting enough protein in her diet. She and the rest of the chickens are not free-ranging dew to the fox that lives in the empty field next to us. I tried Blu-Kote and it seemed to make her want to peck it even more. She is pecking herself on the center of her wing mostly, and the other chickens are pecking her on her crop area, and just below her head on her neck. She is a mess! I heard about Pine Tar but want to know if that stuff really works before spending $10 on it. I have another chicken that is being pecked on her crop area too. Please help!
