Black Spots On The Comb?!

[Ellochicken]

My Buff Orpington hen Sunshine has been getting some black spots on her comb, and I was wondering if it was some kind of disease? I really have no clue, and I'm pretty sure it isn't frostbite because my RIR Penny has frostbite, and it looks nothing like this. They're little black spots on the comb.
Any Ideas As To What It Might Be?

It could be from others pecking or picking on the bird. This happens a lot in flocks. Others peck at a comb to maybe move a bird out of the way and the comb gets nicked. That spot, if it bled even a tiny bit will turn black. My birds combs are all spots like this. LOL My flock leader is brutal on the hens.
