Hi! I encountered a problem like this... many years ago... anyway, my solution was pretty much patience. every day, for about 6 months I would just put my hand in the cage gently. I would then leave it there for 30 seconds - 1 minute. eventually, coming up to the 3 month stage, he started becoming curious and came up to my hand and nibbled my finger. this continued for a month or so, then I slowly moved my hand toward him. I always did it below him so he wouldn't be forced to jump onto my hand. by the time it was 7-8 months, whenever I put my hand in he would automatically run towards my hand and jump on it. he is now a mature budgie and nests on my hand and cleans my nails too (ewww). I have tried taking him out of the age but he just crashes into the walls and injures himself. I'm content and he is too at just a hand relationship (Lol)... Hope I could Help! Elle
