Black on comb--cold damage already??

[vivaciouswoman]

One of my 11 has some black on her comb. I'm attaching pictures. Is this cold damage? Or something else? We have had hard freezes here already.

As you can see the black extends over the back of the column and the base. And there are spots of it on the side too.

Now that we look more closely, more of the birds have black spots on their combs. But this one is the worst. Help????

Pox?

TO me it looks like she has been pecked or has injured it. Black marks like that are usually from bleeding. It should heal in a couple of weeks.
