I can rule out frostbite, mites, damage and infection. Anyone have any idea why Raymon's comb looks like the hamburger helper glove? While we did have some nasty cold days, and a couple of the other boys had a touch of frostbite, I was able to stay on top of it and prevent severe damage. He has been bullied, and is just now trying to regrow his tail feathers, but there are no marks, cuts, pecks or spots where his comb would have been hurt. He is tame and I have checked him for mites, and even put a pan of DE in the coop when snow was on the ground and they weren't able to dust themselves. Not knowing for sure if it could be an injury I can't see, I put him on antibiotics for a month, with no change. I know I am missing something. Anyone have any clue?
