Let us know if her crop is empty this morning.
Just asking - her vision isn't blocked by fluff/feathers is it?
Losing balance is concerning. I would get some vitamins into her. 400IU Vitamin E and 1/4 tablet B-Complex.
When you can, get some photos of her poop. Do you have a vet you can...
How is she doing?
Can you get some photos of her and her poop?
A video of her actions may be helpful - upload video to youtube and provide a link.
Where are you located in the world?
What do you feed?
See if she will drink for you.
