One of my chocolate hens (I think) has a leg that is almost turned out 90 degrees, she wobbles along and it eating and drinking normally but it looks really uncomfortable. The issues is with the upper joint the femur/thigh so splinting has not worked. I administer "physical therapy" on a daily basis which is just joint massage and she doesn't seem to mind and maybe its helping I'm just not sure. Are leg issues common for turkeys? Are there vitamins I should be administering? Any advice would be greatly appreciated. Thanks!
