Black spots on face, pox, injury?

[Spruceroost]

I attached a photo of a rooster I have , any idea what it is and what should I do for treatment? I only caution that he hangs out with 3 other roosters, but the other 2 don't have anything on this scale. Thanks for any help!

That looks like fowl pox to me. That just ran through my flock this summer. If the bird is otherwise healthy, he should recover in a few weeks. In my flock of 7 some had it much worse than others, but they all made it through just fine.

I agree, it looks like Fowl Pox.
