My bird tends to sit in the corner of his perch, at the opposite side of his toy. Should I move the toy? Is he sick or something else bad? He also takes a lot of naps, at least I think he does. His feathers are poofed up a lot when I come in, and his eyes are closed when that happens. His tail also quivers a lot. I don’t want him to be afraid of me, especially if he’s already learned to stop on my finger.
