Anyone know what this is?

[ChickalettasMom]

My rooster has had this spot come up on his comb. Since this pic, it seems to just be getting worse. I haven’t noticed any spots on any of my other birds combs so I’ve been putting colloidal silver on it but wondering if there’s a better way to treat it.

Thanks!

possibly melanosis. Its completely harmless. Think of it as like a birthmark.

That's from hen pecking.

I agree it looks like a pecking injury.

Could be dry pox too...are the mosquitoes out where you live?
Best to leave it alone, it will pass, messing with it could spread it.
