Or to be more specific, her body mass index is what's important, not her weight. A clear photo, rather than knowing her weight, would be more helpful in determining her overall health. Sounds to me like the diet and the environment aren't right and if it's been that way for much of her gestation period...

How long has it been since she ate? Did she eat all the way up until she had them, or quit 3 weeks prior? What's the cool end and warm end temperatures? What are you using 2 heat a 5gal tank? How long ago did she have them? That's all important to know. But seriously you could have been feeding her worms every day and it probably wouldn't be adequate unless you're talking about a 12-14 inch northwestern or something like that.
