As per the vet: "Currently the only finding on necropsy included mildly cloudy air sacs and watery diarrhea in the GI tract. As discussed, histopathology can take as long as 4-6 weeks for results."
The vet is currently out of town and is the only one that specializes at the clinic for exotic birds (which apparently chickens are?). I'm kind of just doing a shot in the dark. I got up every hour last night to make sure they all took drinks of water with the medicine in it. Today.. most are active. Two hens, though, are lethargic and hunching over. I don't think we have found the right anti-biotic, but it still may be a virus that will claim the whole flock. I spent a good deal of money trying to save Paris and I can't do that for every one of them even though I really do adore the little things.
I did buy some tylan today at a local vet supply store. I'm going to try it on the hen with the worst symptoms to see if she improves tonight. Needles seem scary to use on them, but I want to try to save them if i can. They are bantams so I"m going to use .25 cc for three days injecting on opposite side of the breast on the next day.
