I can only assume you mean the comb of your chicken is turning black and that would either be a trauma injury or the result of frostbite. Either way this is not great news but you can use a petroleum jelly like Vaseline on the comb to keep it moisturized. Comb and wattle injuries are not uncommon and unless the bird gets blood poisoning they can survive the loss.

Their Pecker is on their head.
