Sometimes a buddy will help them to navigate too does she have a buddy she can hang with. someone mentioned a bell or whistle to help her find food and water, I know when i want mine in I whistle and they come running because they know they are going to get treats. so maybe you can devise some kind of noise that will help teach her where she needs to be for food and water. Wish you the best with her.The vet just suggested keeping her locked up is a coop or run at all times for protection and making sure she eats.
