Hens comb gone light?

Thank you for the advice! We are in the panhandle of Texas. 40-50 degree days and 20s at night are our typical winter temps. No negative temperatures or anything crazy. I clean the coop once a week to prevent extra moisture. I’m honestly shocked she could have frostbite.

FB can happen at just under freezing.
It also could be a nip from the cockerel.
