I actually got my budgie as an adult...it took awhile, but he's very tame now. I keep his wings clipped because I'm incredibly paranoid and I've actually had dreams about him somehow getting outside and flying away, or flying up the chimney and getting stuck....I just feel better with him having clipped wings. He can fly well enough to get to where he wants to go, but he can't gain altitude very well. He spends every moment that I'm at home, out of his cage. He usually starts out on my shoulder, but then he just HAS to investigate my hair, and he inevitable gets tangled up, and after I detangle him he crawls down the back of my shirt, and when I remove him from my shirt he just HAS to go see the fish, not realizing that the poor fish don't like it when he sticks his beak up against the tank and screams "hello? hello? hello?" over and over and over and over and over.........so I get him away from the fish and he promptly leaps out of my hands and manages to glide right into whatever leftover dishes I have on the table (I'm really bad about doing dishes) so he has to get a bath and then he wants his veggies, but he decides that, instead of EATING them he has to pick all the peas out and roll in them, smushing them into his pretty blue feathers, and then he gets really agitated when I catch him, knowing he's got to get yet another bath......he's exhausting but I love every minute of it.
When I first got him, he wanted nothing to do with me. He would draw blood everytime he bit me (his beak IS small, but it still can hurt when he wants it to). He screamed nonstop. He had a horrendous diet...NOTHING but seeds. He wouldn't touch pellets, veggies, or anything. I finally got him to start eating pellets, so now that's his main staple but he's offered veggies twice a day, and he usually gets some fruit once a day. He talks nonstop....he says "hello", "uh-huh", "yeah", and when he sneezes he tells himself "bless you". Or if he hears someone else sneeze, he'll tell them "bless you" (after he imitates them sneezing, of course).
