We have oneTimneh that has a badly turned foot, he gets around great and is the most aggressive with other animals and birds of our flock. Smarty Pants has no idea he has a problem at all.
Ha, Timber is not particular about walking through his poop either! I don't think greys see it quite like we do... He is in a "hospital" cage now, and I have to keep a towel in the bottom. You can imagine! When I'm not tending to him I'm doing laundry That's why I said I didn't know how you keep up with all of them. He takes up so much of my time and there is only one of him!
