Just wanted to let everyone know that Mad Hatter seems to be doing a lot better. Two nights ago, she jumped and jumped, and couldn't reach the bottom roost. I ended up "cheating" and picked her up and set her up there, and she seemed so happy to be up there. Last night, I watched her pace back and forth, then finally jump to the roost - and make it!!! She is still a bit slower than usual, but when you reach for her, she runs away! Last night she pulled up a huge worm, and although everyone else chased her, she held on, and then finally got herself under a plant and ate that worm with great relish. I can see she is still under the weather, a bit, but she is so much more like her old self that I think she is going to pull through and be okay.
I'm bumping this to say thank you to everyone who offered advice, and also for anyone going through this that hasn't gotten answers, yet...
dlhunicorn - i have read that white clover is also cyanogetic, and know that she was eating that, and banana peel.. i don't think enough to give her cyanide poisoning, but if she found some cherry pits and ate those as well (don't know how many it takes?) perhaps that was what was enough to cause poisoning? and how is your roo doing?
the Poly Vi Sol (thanks, mermaidgoat!!!) and the ACV seemed to really help perk her up. I also gave her plain kefir along with plain organic yogurt each day, with garlic... and also a bit of cod liver oil mixed into that. Not sure which if any of those helped more than the others, but that is all we have done and that seems to have been what helped.
