Hand-reared?

Hi folks, i was just wondering, we have purchased a IRN a few days ago, it was sold as 'hand-reared'. For the first 2 or 3 days so far, it seems scared of us, wont fly to us, wont jump up on our hand or finger, and seems to be scared as it jumps off its perch and flys around the cage clinging to the back of the cage sometimes. Is this common in a Hand-reared IRN as its not with the owner who bought it up hand-rearing it..? Is it just a case that we have to give it time to get used to us more.. at present it is about 14 weeks old.. and we though, being hand-reared it should be okay with humans..?...
Thanks In Advance..:greenyellow:
