The first concern here seems to be to get her back to her prime health. For this you need to get her to the vet to rule out any infections. After that, to start off, give him something he like so that he can recover. Brown rice, carrot, chicken,sweet potato sounds a very good meal for this purpose. You can supplement some products with multi vitamin and calcium based on the vets advice. Many are available at our site. Cerelac is a very good choice as a morning energiser [ any reason you are avoiding it?]. I am sure with love, proper care and affection she will be better in no time.
Do update on the matter.
All the Best.
