Her behavior is as normal, eating and drinking well talkative as always so her behavior showed no signs of any problem,but the color of her comb is worrying me.

It would be good to keep moisture down, yet have good overhead air circulation to allow moisture to escape the coop. Toes and feet can become frostbitten when there are water spills and feet get wet during freezing temperatures. Here is some reading about frostbite:
