It doesn't seem to be an injury to her leg or foot. It's more like she takes a couple steps and then lays down like she's exhausted. Her eyes look good. She is eating and drinking. She does have loose stools and rough feathers. Most of the day she just sits on a perch watching everyone else. But when she does get off it seems like she takes a couple steps, like a shuffle and then plops down on the ground. I have no idea what could be her problem. I don't think it is a physical injury to her leg or foot, I've checked many times. Any ideas of what it could be?
