My BO roo has developed a black scabby-looking patch on 3 or 4 out of the 6 or 7 little triangular "spikes" on his comb. If we were in the north, my first guess would be frostbite. But I'm in Florida, and we haven't even gotten below 30 F here yet this winter. They are randomly scattered, I'd say on spike #2, 3, 5, and maybe a little on 7. So it's not all toward the front of his comb, nor all toward the back. I'll see if I can get a picture. But in the meantime, any ideas? It's NOT Fowl Pox, I've already had that run through the flock and it cleared up. Is there some other nasty disease that makes black spots on combs? Or is my dominant hen just biting the crap out of him?
