I feel like a broken record but ESPECIALLY for rehabbing you simply MUST have a GREAT bulb. Go to reptileuv.com and buy a megaray. If you need help call Bob MacCargar (his number is on the site) and he will help you over the phone.
You temp in the basking area should be 110-120. Explain your setup and needs to Bob and tell him I sent you to him

You can mix a slurry for the animal..using pedialyte (non flavored and non colored) baby foods of chicken, turkey, green beans, squash and sweet potatoes are all aceptable. Probiotics are a must as well (see reptileuv.com for more info and sales). You can mix the whole list together.
Try to hand fed them with the syringe by putting the food on her nose or the side of the mouth without forcing the mouth open.
Use this technique until the animals are full and healthy, and before you knw it--they will be eating on their own fine.
But please adjust their heat and lighting immediatley.
