Well I am maybe not Alen AXP but I do have a question before I answer. Does your budgie trust you? Did you just get it? Because when I got my budgies, They always stayed in one place without moving. If the answer to my question is yes then you should just give the budgie a little time to get used to the environment If he is scared of you, you should ASAP start interacting with him/her. He will never get over the fear of you being close to him if you don’t get close to him in the first place. Try spending a good minimum of ten minutes twice a day with him, talk, try giving him millet… When people (like me), believe that you should let your budgie a day or two to get used to where he is, then stop it. That only lets him get used to the fact that outside_cage=danger & inside_home=safety, But that’s exactly what you don’t want it to believe. I hope this helped :).
