thankyou, that was very helpful! I wasn't sure before how to tell whether my bird was healthy or not. There's no way I can catch him, even though I let him out of his cage for aleast an hour a day, I have him trained to go back in his cage when I tell him to so I've really never needed to catch him. I think I'll get him a rope perch and a sand perch to help out him feet.
Thanks again!
