Hi,
One of my ~1.5 year Plymouth Rock hens started to show paralysis signs three weeks ago. She could hardly walk then, but still managed to move a few meters, walking on her ankles. Gradually the paralysis became more sever. Now she can only drag herself a bit, her toes are completely curled together, sometimes one leg is stretched behind the body, and today I noticed for the first time vibrations in one leg, when she is trying to move.
The strange thing is that apart from that she is totally fine. Her comb is red and thick as always, her feathers look fine, eyes always open, head is not sunk into the body, and she makes normal sounds. Moreover, she even laid one egg about 10 days ago (the egg was fine). And above all, she has excellent, constant appetite (though she doesn't drink when I offer her water, so I'm putting water inside the food).
When I noticed the paralysis 3 weeks ago I immediately started administrating amoxicillin and norfloxacin, since I was sure I was going to lose here in a couple of days. I made afterwards bacterial examination of her poop which came negative. Also, no parasites were found in her poop.
Also by manual outside inspection she doesn't seem to break any leg.
Has someone experienced such a case? I have passed over all diseases in the book I have and found none which suits the age, signs and duration of my case. The closest were Marek and acute Calcium deficiency (I can recall the name). I would appreciate your help!

I'm not much help with knowing possible causes but @Wyorp Rock @Eggcessive
@R2elk @casportpony
may be able to give you some suggestions. Any current photos of your hen would be appreciated and possibly helpful.

A few more comments:
Her poop is diarrhea now, but I am quite sure that in part of the last 3 weeks it was solid.
I feed her with sprouted grains (wheat and etc.) and vegetables, and in the last few month didn't add egg shells as I usually do. All my hens are hardly laying nowadys, for about to months or more now - so she was 100% not laying many eggs prior to the paralysis.
I added a photo of the hen.
 
It is possible that she had riboflavin deficiency that progressed to lameness, but Mareks disease could be possible. If you lose her or put her down, it would be worthwhile to have your state poultry vet do a necropsy and test her for Mareks. They examine the feather shafts and test any tumor tissue found on nerves or organs. Here is a list of state vets to contact:

Here is an article about riboflavin deficiency and another on Mareks:

Sorry to hear about your hen.
What do you feed including treats?

I agree, it may be Marek's disease that is affecting her and trying vitamins (E, B1, B2) may give her a boost. Some chickens are able to overcome their symptoms while others continue to decline.
@Akrnaf2 may be able to help you if the symptoms are caused by nutritional deficiency.
