Hello and :welcome: to the forums!
Congratulations on your new friend
It's important to remember that even if you budgie is handfed, he is going to be stressed and scared in a new environment for two weeks or more. Even with budgies that were handfed/raised, they take time to settle into their new home
It's advisable that you don't touch him until after this time, and use this two-three week period of time to let him settle in, get to know him, and let him be comfortable with you. Then, you can start to get him out on your finger and such. As he gets more comfortable, he will play with his toys and explore new foods.
Good luck with your new boy and I hope to see pictures of him soon
It's great to have you with us and if you have any questions, please ask as we'd love to help :wave:
Hope to see you around!
