That's up to you. If you think she's struggling too much and maybe not getting enough to eat or drink, then yes, I would do your suggestion. Could you bring in another of the more "calmer" ones to be with her if you do that?
If you do, I'd keep the feeder/waterer in the same spot. If she's having vision issues, by now she'd know right where those are.
I have done this in the past with a weak one or two. I feed them mash mostly and put a couple of drops of vitamins in it every other day. I also put powdered probiotics in their water, every other day. After a couple of days of this, they usually seem to come around.
