I'm working on both at the moment - I think her former owners didn't really do any research into how to look after her - she's affectionate, I know she was hand raised, but the sunflower seed obsession and the fact that she is very needy and bites if you stop patting her (not as much as she used to now though, she hasn't drawn blood in the last couple of weeks actually) indicates to me that she was pretty much the boss with her old owner - it looks like she got her own way a lot of the time about things that aren't good for her. I could be wrong, I know i'm a total noob here. On the other hand, she whistles for attention instead of screaming, and lifts one leg when she wants to step up, so she has been taught a few manners.
She has free range when I am at home, her perch has a ladder and one of those ropes (stiff, coiled, doubles as a toy and a perch) that she can use to get down, (she's clipped, and I think she has been clipped her whole life - she very rarely jumps off her perch, it only happens when something startles her, or in one case when one of my daughters friends tried to pat her when I was out of the room after being told not to go near her - she attacked him, so I think he believes me now about her being a tad vicious lol - he's 8, she nipped him on the hand and launched at him for coming too close).
I bought her a cage for when I am not home/ for unsupervised playtime outside that is pretty big. Her balance isn't great, so when she is in the outside cage she has swinging toys, and her food is put on one of those hanging bamboo toys that have little circular bits cut out, so that it moves when she is trying to eat - its stage one of an obstacle course i intend to build between her perch and her food so that she gets more exercise. She was a total perch potato when I first got her, but she is getting used to being able to wander around now. She still spends way too much time sitting around watching tv though lol.
