The blackened parts will dry up and fall off on their own, so next winter their comb and wattles will be a little smaller and hopefully the frostbite will not be as severe as this winter. Chickens restrict blood flow to the comb and wattles to conserve body heat, so the tissue freezes and becomes necrotic (black), and will dry out and fall off.
Interesting about the blood flow, that makes sense!
