Powdery white combs

[Belovedturkey]

My chickens seem to have white stuff on their combs, I saw it on one so I checked them all and it was on all of them. I got the best pictures I could. My hens don’t seem to be acting weird but is this something I need to treat? My flock did have scales leg mites recently if that’s related, and should I be concerned because it’s about to get colder here will this make them more sensitive?

Looks like dry skin.

Is the humidity fairly low?

I'd just watch them for now, see if the dryness improves as the winter months pass.

The humidity is definitely lower than it was, I’ll keep an eye on them
