I have seen all kinds of things cause ataxia and semi-paralysis in chickens, ducks, peafowl, turkeys, and guineas. Yeah, sometimes it's Marek's in chickens, but worms, bacterial infections, vitamin deficiencies, mineral deficiencies, and coccidiosis can cause it too.
I sort of skim read the thread (sorry ).
If this were my hen I think I would get a baseline weight, then weigh every day to watch for weight loss.
For worms I would treat with Safeguard orally for five days. This will treat roundworms and almost all other worms.
Because she is laying eggs (please correct me if i am wrong), and walking on her knees, I would give her some calcium citrate. Google cage layer fatigue or calcium deficiency in chickens and I think you'll see why I suggest this. Not long ago I had a duck doing this and the calcium really helped.
B vitamins won't hurt, and they might do some good, so I would probably do that too.
I saw one poop picture and I think it had too much mucus too me normal, which could be from the worms.
