I handween my 3 months old, now 6 months, almost every day. That's how you tame them enough.
While it is emotionally satisfying for the pet owner to have a dependent budgie it is not good for the poor bird.
Selfish humans do NOT really love their birds because true love is sacrificing yourself rather than exploiting your pet because of your feeling of love and affection.
The same goes for human relations. People do not understand what love really is.
