Oh dear, you are having a bad time of it at the moment! I guess you could consider yourself lucky only to lose one girl if a predator got in but still very upsetting. The bald swollen belly on this girl says she has a serious internal problem that has been developing for weeks or months. Do you have her isolated now and is she still unable to use her legs? What does her comb look like? Is it plump and red indicating that she is ovulating or pale and dry looking? Is she still eating?
What does her poop look like?
Can you post a photo of her whole body including her posture and face with comb?
My gut feeling is that she has a terminal reproductive disorder (salpingitis and/or internal laying) which is getting towards the final stage and you need to prepare to end her suffering, but without seeing her that is a hard call to make. The fly strike, horrid as it is, is just a recent secondary development. The inability to stand or keep herself upright is seriously impacting her quality of life and if I am right about what is inside her, there is almost nothing you can do about it. The only option would be very expensive and risky surgical intervention which would most likely run to thousands of $ to remove the mass and probably her oviduct with it (if you can find a vet capable and willing to do it), with no guarantee of success and probably hormonal implants for the rest of her life if she survived the surgery.
I believe @micstrachan has been through the above with her hen and may be able to advise better if that was something you would consider. Personally my funds do not run to veterinary treatment for my chickens.
I'm sorry to be so negative about her prognosis, especially when you have done so well in tackling the fly strike. If you had caught things a few months ago when they were just starting to go awry, treatment might have been successful, but usually by the time these things become apparent, it is too late.
Ordinarily for a bird that is struggling to support itself, I would suggest a chicken sling/hammock but that would probably still put pressure on her abdomen and make her uncomfortable.... you could try it and see. They can be made from everyday items like the one illustrated below...
It is important to adjust the fabric so that the hen's feet can touch the ground otherwise they panic. Pots for food and water can be clipped to the front of the box within easy reach and a third hole cut in the fabric under her vent to allow poop to drop through.
If you google "images of chicken slings" you will get lots of other ideas, both DIY and quite professional looking.
Good luck whatever you decide. If she loses interest in food, then I would definitely recommend you to euthanize.
