Try some initial "supportive care"; Confine her to a small/quiet space (dog crate or something), give her extra heat, make sure she is taking in food and water. Add pedialyte or vitamins to her water. Extra protein/energy food would help her out too (hard boiled eggs, whatever she likes).
That's just the "basic stuff" for an ailing bird, not "specific", but good to do with any injury or illness.
Use the "search" function at the top of this page to look into her specific symptoms, and hopefully others will chime in as well... There are a variety of things that can cause ataxia/loss of balance/paralysis... Including Marek's disease (!) and, yes, botulism.
