Actually, you shouldn't hold it at all, or else you can get your scent on it and the mother will abandon it. However, if it has already been left or it is domesticated and you need to hold it it should be cupped in your hands.
after you eat it and it is back or you can tame it
In the second week when it has grown some feathers :D
about fourteen days after he hatches, wean it slowly after fourteen days, go slow!
you can start trying to hold your budgie after a week 2 weeks after you have got it. if it will not sit on your budgie then do not start chasing it around the cadge.

It doesn't matter. just wash your hand really good before and don't hold them for too long. after you are done holding them, set them back by their mom so they know everything is ok.
You can touch them when they are firstborn but their mom must be at a food break. (Not recommended for those with no experience) However, you may hold them when they are two weeks old.
Baby girl can hold it for a while but it's NOT GOOD it can cause a bladder infection and i don't recommend it...you shouldn't push her limits.
It would be alright as long as the parakeet does not feel sick or frightened at all. If the y feel frightened then the parakeet might die.
It holds it for 4 months
