My Cream Legbar roo's comb is a mess from frostbite. I think he's going to lose all but one point -- not just tips but the whole point -- and the blade. Several of the hens -- the ones with very narrow points -- are losing a few tips. I've been rubbing all my chickens' combs with a mixture of mostly coconut and some olive oil, as even the non-frostbitten combs look dry. Neosporin sounds like a good idea for my roo. The blade is blistered and I'm afraid to touch that part. I think there's a spray version of neosporin?
