If you provide her a vitamin and calcium supplement at every feeding, that sounds to me like too much supplementation by about 4x. But I don't keep vieleds, so someone here who is an experienced breeder of vieleds can speak to her nutritional needs with more accuracy than I can.
I am concerned that her foot looks severely swollen. It could be gout, or she could have injured it somehow. The bumps on her rib cage can also be a sign of either nutritional deficiency or injury. I would suggest a visit to a vet to check that foot.
