She is now back in the coup and pen full time. Here she is (the red one) with two of her friends a few days ago free roaming in the yard.

She looks so much better now with many feathers, including her fluff, regrowing. Her limp only shows up as she skips when she tries to run. Thanks again for all the well wishes and great ideas. Baby aspirin, hand feeding her, and giving her a mirror while she was isolated led to this great outcome. We look forward to her laying eggs again in the not too distant future.
