I have two golden comets that are about the same age. One of them Stella combs and wattles have completely come out and are red and she seems to be doing good but my other one Lillie her combs and wattles seem to have quit growing. They are just a pale pink and barely noticeable. Lillie's behavior has seemed to change also. She is staying away from the rest of the flock. She lets you pick her up and seems to be eating and drinking like she should but doesn't seem to act like the other chickens. I don't know what to think. Lillie was the smallest of the chickens that we got and that is why I bought her, she was just so cute. Do I have a problem ? If so what should I do.
