What's the temperature where you are???

[MROO]

10 degrees here. Gonna be -4 next two nights. Chickens are getting pretty good frostbite on their combs. Coop is wide open into the run so I don't think moisture is causing it.

Warm some Vaseline on your fingers and gently rub it on their combs and wattles. Be careful of any already showing signs of frostbite, as the skin will be tender, but the Vaseline should help stave off further chapping.

I cannot believe the humidity is 72% though!

Is that very high or very low for where you are?

The moisture is in the air. Try putting a little slightly warmed Vaseline on their combs & wattles. Just be sure to do it very gently, because frostbite hurts!
