Both of our roos have frostbite, and I'm wondering how to know if it's serious. Our cream legbar has it pretty bad on both comb and wattles and they are quite gray. The swelling seems to have gone down. I saw some blu-kote at TSC and I'm thinking I should have snatched it up. How do I know if it's healing or if it's going to make him sick? Does anyone have pictures of what it looks like as it heals and what a bad case looks like, that needs treatment? Thanks for any advice!
