Why does my rooster have a black spot on his comb?

[Platy04]

A while ago I noticed a black spot on my rooster's comb. My rooster appears fine, he's acting happy, drinking, and eating. Should I worry about his comb or not?

Frost bite? Mites/fleas? Scabs from fighting? Most likely not much is wrong, but you need to ascertain what is wrong to be on the safe side.

Looks to me dried blood or some frost bite. My roosters get this too, but are always okay. Put some petroleum jelly on the comb and the blood should come off in the next day or two. Or, if it's frostbite the jelly will help seal out the cold preventing more frostbite.

Thank you!
How low would the temperature have to be for chickens to get frostbite?

It looks like peck marks to me also.

It's really not the temperature that's the problem, it's more of the ventilation of the coop. Sure, if its sub zero temperatures then you'll have some, but frostbite can also happen if it's moist and cold in the coop.
