Black spots on comb?

[daxigait]

One of my roosters had these black spots on his comb this morning. I have been monitoring the coop for temperature and moisture since it is my first winter, but so far we have not had that many cold mornings, and the interior of my coop is insulated and has never been below freezing so far so I don't think it is frostbite, but I am a newbie.

Looks like a pecking wound. Nothing to worry about.

Thanks. My other roo definitely rules. By next winter I hope to have a second winter coop and run so I can separate the less dominant birds into a separate flock.
