Is this a concern?

We noticed yesterday that the wattle on one of our girls looked a little marked. I thought it was just dirt. Today it seemed to be more of it. We took some water and it didn't come off. Can anyone tell from the picture if it's an injury, illness or nothing at all?

Thanks in advance

It could be the beginning of fowl pox.
That looks like a comb.
