Mr Bob's comb is turning black at one end

I noticed just now that our roo's comb is turing slightly black at the end. Hes a black australorp and his comb has been red for 2 years now but today I noticed the end furthest from his head seems to be turning a black color...any advice etc?

Last winter we had an especially hard freeze that lasted a week! 10-14 degrees for a week in TEXAS! We were blessed that everything did survive, but the combs of my 2 roosters eventually turned black and parts of them fell off. Our black ostralorp was affected the worst, but now he is fine, he just doesn't have any peaks on his comb...just flat and round. I know that it is a good idea to coat the combs of chickens with vaseline, to protect them. You might try this, but first I would apply a coat of antibiotic ointment just to be safe. Keep a close eye on it. I'd love to hear what you find out!
