My chick is 8 weeks old and has exhibited weak legs starting about 2 weeks ago. I forced her into a chick sling for a week, which she would stubbornly escape from. On Christmas Eve she was up walking again. She showed weakness but overall no pain. The days prior she was using her beak to drag herself around so I was very proud of her progress! I returned her to her siblings after two weeks of separation but now she seems to be struggling again. After close examination it looks like it is her hock. When he walks I can see it rotating, almost bow-legged. It gives out and she is forced to spend a greater deal of time sitting. Any ideas of how to fix this injury OR what it might be? She has been separated from her siblings once more, against her will of course. I want her to get some rest and have first dibs on the feed/water.
