You've done all you know to do right now. I've been struggling with a situation with mostly 2 of my girls who have been doing weird things since the middle of March. I did all I could think of to do from Vitamin B-complex, calcium gluconate and even tried Baytril. The problem is slowing down but it never stopped and I still don't know what is wrong. They're still alive and the problem has slowed down quite a bit but I'd sure like to know what is wrong with them. They never stopped eating and drinking though so I know how worried you must be.
I just went back and read your post from the beginning which I should have done in the first place. I think, since you mentioned poison, you ought to try some activated charcoal and try to flush her out. What have you got to lose? I don't think it can hurt. You get it at Walmart in the vitamin section of the pharmacy dept. I just cut open a capsule and put it in the drinking water or if you can do it push the capsule down her throat. It's good to have on hand anyway for other animals as well as humans!
