She looks just fine.

How much ventilation is in your coop? You need to keep the coop DRY and very well ventilated. With 3 birds, you want as close to 3 sq ft of ventilation as you can manage.
Don't keep any open water sources in the coop during cold weather.

I see there is a bit of black. This is what frostbite would look like. I just can't see how your hen could get frostbite. I live in Michigan, about 80 miles north of Detroit. A couple of my Rhode Island Reds got a little frostbite one year, but it was a long and unusually cold winter. I don't think it gets cold enough in Tennessee to cause frostbite on the comb.
