I have one cockateil that is was hand raised and one that was not. Bob (the hand raised one) was very nice from day one.(still is!) and Chickie (not hand raised) was not so nice at first. But after a little time learning from Bob and a lot of bitten hands living through the pain (took a little while to get used to! lol), Chickie turned out to be a real sweetie! If you have patience and dedication to the bird, it should turn out just fine!
