My BO rooster’s wattle has been slowly turning black over the past month or two. His comb is in good shape, there’s no swelling and he doesn’t seem to be in pain or ill in any other way. The coop is draft-free, dry, and has good insulation (they’re very spoiled) and none of the rest of the flock (only 7) has this problem. I read somewhere that wattles like this have been frost-bitten and if they turn black gangrene has already set in (and they require surgery). If that was the case wouldn’t he already be sick? Any advice would be appreciated…he is my 3 year old’s special friend; I’m hoping we can keep him. Lots of questions…thanks in advance for your help!!
