Here is the video that you posted on that thread:

Does she walk on her hocks or is she dragging her bottom on the ground? It could be that she has a vitamin B2 deficiency, and is walking on her hocks. I would give her 1/4 tablet daily of vitamin B complex for humans crushed onto some of her feed or a treat to see if it helps. If that is not the problem, she could be suffering from a spinal deformity pinching her spinal cord, or possibly Mareks disease. This is just my amateur opinion. A vet might be of more help.

I believe she may have injured her back.
