After two weeks since my new hand raised budgie came home, I've just been able to get him out of the cage (perch on my finger) without too much resistance from him trying to get back on his cage perch. Now I've tried bonding with him and trying to get him to eat out of my hands but whenever I try he tries to flee or doesn't move. I've tried so many techniques and it's not working. What should I do? Should I take him back to the pet store to get an exchange? Shouldn't hand raised budgies be able to eat out of my hands and want to bond right away?
