Is this frost bite?

[The cheek coop]

We have had temps as low as -5 degrees Fahrenheit for the past few nights. I noticed this on our white leghorn this morning and was concerned it was frostbite. I took these pics this evening when I returned from work.

Yes, it's mild frostbite. Don't mess with it.

That is early signs of frostbite.
