Okay, so one of my hens has something on her comb. I'm not quite sure what it is, but my first guess would have to be frostbite. The only problem with that is, it hasn't been cold enough for her to bet frostbite, and none of my other chickens have this on their combs either. Does anyone have a good idea as to what it may be? I don't know what type of chicken this is, it was one of my aunts chickens. I do know that it is a meat bird. I have three pictures, that I took this morning on my phone. I first noticed it about two weeks ago, and i figured it was from the rooster. It wasn't nearly as bad is it now. It's only on the left side of her comb. That's about all the information I can give you.
