Does this look like it's from a parasite?

Trying to figure out what the brown crust on my chicken's comb and waddle are and figured the fine folks at backyard chickens might know. Does anyone know what this might be from? Is it reasonable to think it might be from mites/lice?

Can you get closer pictures? Have you tried to wash it off?

Is it a touch of frostbite? (This is what it would look like a couple weeks after the cold)
