I have a 6month old bantam roo who has one of the points on his comb black (guessing frostbite). I know u have other posts on it but i have questions. (1) does it hurt him? he seems fine. (2) what should i do? it's warm in the coop (heat lamp ect), he's the only one with it. (3) Can i prevent it? Oh, and if you say ointment, what kind? Thanks for your time.
