My hens are about 6 months old. They're not laying yet, and are quite healthy. However, one has a black scabby growth on her bottom beak, right side under the nostril. It looks like a piece of dried up chewing gum, but it's actually her beak, looking quite disgusting. She's eating just fine, and it doesn't seem to bother her, but I'm afraid it's getting bigger and that eventually that part of her beak will just fall off. There is a small hole in the beak just under her nostril above the black section. She eats regular layer crumbles, and treats from the garden. She has a roomate that does not have the same problem. Is this beak rot? I've heard of it with hummingbirds, but I change their water quite frequently and it never smells or looks bad. These are my first chickens and I don't want them to suffer because of my lack of experience! Any advice would be appreciated. Thanks!
