Black spots on comb

[wbjdmd]

I have a hen that I estimate is 6-7 months old that has black spots on its comb. I just noticed it today and the hen seems otherwise healthy. I have two other hens in my flock but haven't noticed this on them. What is this, do I need to worry, and what can I do to remedy this? Thanks for any advice!

My hens have some spots on thier combs and they seem fine, but if it seems like it hurts them try to find a vet, but i wouldnt worry

I have seen this posted before. If you do a search above maybe you can find some answers. I have heard anything from others pecking unprotected areas such as the comb, to mosquito bites.
