Rooster's comb and wattles turning black? Help!

[ChickenKeep01]

I have a japanese bantam rooster who is just over a year old and yesterday i noticed he had some dirt on his comb so i just left him, but he still had it on there today so i started helping him get it of but then i realised that he didnt have dirt on his comb/wattles but they were turning black! i have no idea how this happened he is in a coop with 1 hen and 4 chicks (all of which are his) and right next to it (separated) is a coop with 4 isa browns, 1 australorp, 1 frizzle (who is also a rooster but his comb is fine), 1 silkie and 1 pekin bantams. I have seen no blood or worms in their droppings and he doesnt seem to be acting any different to normal. I don't know if this is important but i live in Australia where the winter solstice had just passed and the days are still getting colder. If needed i can provide some pictures.

After doing more research i found he has frostbite i have put some Vaseline on his comb and ventilated the coop better is there anything else i can do?

Sounds good! Also it could be someone picking on him and he could have little scabs on his comb.

Pictures can be helpful. Frostbite can be common in very cold temperatures in winter, especially in roosters with larger combs, and high humidity. Combs are very painful in frostbite, and should not be massaged or handled much. It may take days to tell how much damage has been done, and eventually points of the comb may become rounded off.

None of the others would be picking on him because the chicks can even reach that high and he is easily the boss of the hen thats with him

Eggcessive i will be able to get some pics in a few hours

I usually do not use anything on a frostbitten comb, since most have been on roosters who have not liked being touched, and so as not to damage it or cause pain. But some use a water soluble vet spray, iodine, or some antibiotic cream, although it should be just gently dabbed on and not massaged.
