That looks painful. Try aloe-verra its really good for scrapes and scratches on parrots!
Apply a decent ammount of it on the problem area. If you dont see it getting any better in a few days id go see an avian vet about it! They may give you some pain killers or cream or antibiotics if its infected! Hope that helps! Keep us posted on her foot! I hope she heals up nicely!
Its looking much better today than it did a few days ago did you manage to get some aloe-verra gel?
