Fuzzy, you know Lurch took most of 5 years to decide I was worthy of his trust and love but he got there, even though he'd still bite if offended. I'd say Chico is working his way there on his time and you'll be great friends except for the occasional corrections he thinks need to be made. He looks totally happy with his lot in life and is acting out and talking do to being happy. They certainly don't make that kind of noise or run around even though handicapped if they aren't. I lost 30 percent range of motion in my right arm after I broke basically the elbow joint in 09 and the therapy ladies made me a brace and had me doing all kinds of exercises to bring it back. They Made me wear that brace every night and every week they'd straighten it out a bit more and yep it hurt. By about 5am I'd give up and take it off because of the pain. BUT I eventually gained back most of my range of motion and was down to 3 percent loss when I was released after 4 months because it was stable, not necessarily fused together again, but stable. If you can do something similar for his feet and neck without hurting him it'd help his quality of life and being able to do bird things but he's doing great now as is and has adapted like all critters do.
