I don’t know the she of this African grey
but one of her feet are turned around
she’s can’t stand on flat surface
If your bird has become injured or is sick, you need to take her to an Avian Vet as soon as possible. If she has always been this way, then is it either a deformity from the egg or an old injury. A Vet can still help as surgery may be possible or the Vet can at least suggest ways to make the bird more comfortable and get around the cage more easily.
Thank you for asking Lafeber,
