4 weeks ago I bought a 7 week old hand fed budgie who came right on my finger. In the 4 weeks he has become less tame than he was. When I go to take him out he tries to get away - the last 3 days he has pecked at me. When I go to put him back, as soon as he sees his cage he tries to fly to it (wings clipped). I feed him millet every time. How can I get him to want to come out of the cage and be with me?
