What is wrong with my roosre's comb?

[Grondel Farm]

Medium white patch on rhe left, start3d out 3 days ago and now has a raw looking center... Also faint whitish blotches and few spots on his left side. Thought it might have been related ton3 cold nights, but had not gotten better on right, and left seems to have spthis.
He is otherwise healthy acting normally -eating, foraging, protecting his glock.

Fungus? Or Favus? What should I do?
I am new at all rhis.
Any thoughts very much appreciated!
Thanks in advance...

What did you mean by "spthis"?
He has a large comb, how cold did it get? Larger combs are more at risk for frostbite. I can't zoom in close enough and get a clear look, doesn't really look like favus from what I can see. The larger spot looks like some kind of small injury, I would just keep an eye on it. You can dab a bit of iodine on it or apply some plain triple antibiotic ointment if you feel it needs it, but I'd probably leave it alone. Frostbite usually affects the tips of the combs more than the lower parts first. If it were mild frostbite then the spots would turn dark and may slough off eventually. The whiter spots may just be dryness, or from small pecking injuries that have healed, when scabs fall off the underneath tissue will be paler for a while. Large combed birds do tend to get more injuries there, rubbing on fence or wire, feeders, pecking, etc. If it's dryness you can apply a bit of coconut oil if you want.

Thank you for your quick reply!
Spths = Spread....i hate texting!"!
I thought I saw a piece of the white patch on the right side waving in the breeze earlier, so that was perhaps a scab coming off as you suggested. Ill keep watching, then use neosporin if no improvemt tomorrow.- On both sides. When I pick him up to look closely, will I be able to see scab, and scabs or softer fungus on the left.?
