Okay - I'll spray again and then apply the neosporin. I have to add that I have been using a homeopathic remedy as well - I took a couple of classes in traditional homeopathy, one specifically in first aid. I added Belladonna to her water, since that remedy seemed to fit her symptoms the best. Have no idea if it helped, but I believe it did. I've been giving her meal worms, bird seed and some layer pellets, and have offered her plain yogurt as well. I'll see if she's interested in sprouts tomorrow. I have a space heater in the room, so it's a balmy 75 degrees. I tried using a wet paper towel to clean off some of the pasty butt, but it's pretty caked on there. I feel bad for the healthy survivor alone in the coop - it's supposed to go down in the single digits overnight for the next couple of nights.
I'll post tomorrow after the topical has had a chance to work. Hopefully she will make a full recovery.
