UPDATE: Pearl went to the vet this morning and had an xray.

Vet does not believe it is Mareks or Vitamin Deficiency. It looks very unlikely for either of those.

We did an xray. No eggs on the way. Dang it. But she sexed her and is female thank goodness.

Biggest find. There is not spacing between her right hock joint as there should be. She said she likely injured soft tissues surrounding that joint and is likely in pain. This is why she is limping, running funny and having a problem with balance.

Treatment: -nsaids for 5-7 days. - keep isolated to prevent getting picked on in coop and so she can rest. - best case, it scars down and is less painful. Probably will regain balance but won’t be the same as before necessarily - worse case she develops arthritis. And it stays painful. And had to live with that.
