Black spots on combs.

I've noticed black like deformations on a few of my chickens. Does anyone know what this is or how to treat it?

Can you post a photo of what you're seeing? It would be helpful as there are lots of things it could be.
Are there any other symptoms?

The info from MSU states it all. You can put iodine on the black nodules to help dry them out. Since it's a virus and not treatable, it'll take a months time more or less, to run its course.
