I'm sorry that she's not improving.
If you've been giving extra calcium citrate this whole time and she's laying regularly, I would taper that off.
Have you tried putting her in a sling to get her upright?
Hens have a pecking order and it would be normal for the healthy ones to pick at one that is weak like this. Unfortunately, this seems to be the nature of things with hens. Hopefully she can still be near them and with them supervised so she can have the stimulation she needs.
