This girl is an old ex-batt rescue hen. We have a couple dozen of them. Some have a few scabs on their combs, and some are missing a bunch of feathers, but this one is different. She has a really sad looking comb with poor circulation in the tips and a lot of scabs. No pus, a tiny bit of blood on one scab/spot, and puffy eyes that look half-closed. Good appetite and great feathers and vent. She's looked this way for weeks and weeks. But a couple chickens recently passed away and we also found out we have some lice. Coop and chickens treated for lice, and antibiotics in water now for respiratory thing going around. This one has no prolapse or issues of any sort that are visible except for the comb, the eyes, and a little bit of tiredness. She goes to bed pretty early and seems to be getting more tired.

I've looked up fowlpox but I'm not convinced. She doesn't appear particularly low on pecking order. I think she's really sick but just wonder if anyone has an instant "I KNOW!!!" when they see the pics. Thanks.
