Hi Crystal,
Every bird has their own personality, although this isn’t what one expects from a hand fed bird, especially if it is a male. The females are more likely to act this way. I do have to wonder if the bird was truly hand fed. It sounds like he was either parent raised, or if he was hand fed, he was in an aviary with a lot of other cockatiel and wasn’t handled or socialized. Hand feeding alone doesn’t make a bird trust people. They need to be handled as well as being hand fed. Anything is possible, but most likely this is how he is going to be. I’m not saying give up. I would recommend that you read our pages on behavior as well as taming and training. It might shed some light on something that you are inadvertently doing that causes him not to fully trust you. Always keep in mind that they are a prey animal, so if you reach for him from behind or try to pet him from behind, he feels like you are a predator trying to grab him. Also, if you are hesitant about handling him, it can make him fearful because it causes him not to trust you. Hopefully our behavior and training information will help you out.
