About a week ago we noticed her babying her leg. she hops around holding it up. If she puts it to the ground, she immediately pulls it up and out comes the wing to take the weight off of her leg and regain balance. Almost how we would treat a sprained ankle. There is nothing obvious, no wounds and when I hold her she lets me rub it, squeeze it up in the thigh, even move it and she does not complain. Anyone?
