looking at those pics, I can't see any swelling. But has she only 3 legs?
Really don't want to sound harsh or cruel, but I'm not sure you should keep any more animals, and certainly don't start your own pet sitting service. If your parents aren't willing to get a sick animal to a vet, they...
I think maybe the issue is you're not being very clear on what the actual 'issue' is?
Does she look healthy, as pointed out but ignored, swollen toes. Not just ignored, but swiftly onto is she gravid? When pointed out you'd ignored the first bit, the toes, you then say 'let's get back to what I...

Not sure how to use the syringe you have. The liquid calcium I think can fe be given via a needle by a vet or injected into a feeder, into a cricket.

Read the care sheets, lots of good...

How long has she been plump and dragging her tummy?
Do you have a good vet you San go to if need be?
If you search the forums for laying bins, posts...
