Small flat black areas on the comb are usually akin to bruises. They get them from banging into something and pecks from the other chickens.
Raised black areas that look pus-filled can be fowl pox. You can do a search here on BYC about fowl pox.

a picture would help a lot, but it might be frost bite.
