Poor Roberta.
I find that chickens her age (2 years+) do not commonly experience viceral Marek's as much as younger chickens. Can they still get it? Yes. But generally in older birds we see wasting, gradual decline, sometimes ocular problems and secondary infections. The paralysis is somewhat less common in older birds.
Does she still seem to demonstrate paralysis?
Please do check her ASAP for being egg bound. It can cause the symptoms you describe. If it is egg binding, you can help save her life.
Is there any chance she may have eaten anything moldy or rotten? Has she had access to a compost pile or bin, or any areas with standing water such as a pond, stagnant puddles, a ditch? Could she have eaten any decaying materials?
Is there any chance that she may have gotten into any moldy or bad feed?
Is there any chance that she may have eaten any lead? Lead is somewhat common on old homesteads, etc.. or in places where hunting, shooting, or varmint and/or bird hunting has happened. A single lead BB pellet can cause lead toxicity. Leaded paint chips and old parts in the soil can cause it too.
If you are certain she is not egg bound, keep her hydrated. Feed her nutritious and if you'd like you can offer B vitamin supplementation in her food. B is water soluble and won't harm her, and it may help her if she has nerve damage (though it can take a long time to heal).
