Pullets with gray on combs

[esmith27]

2 of my 6 pullets have a bit of gray where the developing comb meets the nostrils. We got about 8 inches of snow 2 days ago and it’s been consistently in the 20’s (Fahrenheit) and below the last several nights. Could this been frost bite? If so, what should I do?

Is it on the beak itself or the skin? It looks kinda like the beak may have a bruise on it.

From what I can tell it’s on her beak, it might be from getting pecked. She doesn’t seem to be low in the pecking order though so that’s why I was confused

I don't think that's frost bite.....looks more like peck mark or a wound from trying the get thru some fencing or mesh.
I'd just keep an eye on it.
