Update:
I took her to the vet today. Internal perasites caused the comb animia. She has mites/lice and her face is swelled up because she has been scratching it.
Thanks for the suggestions guys. It doesn't look like the pictures of the different pox issues. She doesn't have any scabs like that. This stuff started right after it got cold here. Do you thing that had an effect?
Also, her coop mate is fine. Bright red comb, laying eggs, there is nothing...
I am a new chicken owner. We have two hens is our back yard one of our hens has been like this for about a week and a half (see pic) but I have no idea what the problem is. It looks really icky, but when described to other chicken owners they tell me she is just molting. It looks awful ugly...
