Millet is like ice cream for parakeets. I noticed that they forget their fear of hands if they see millet! They must not see the hand anymore! Example below:
The only tame bird here is the one on the bottom. The two on the top part of the picture are not tame at all. They couldn't resist seeing my tame bird eating the millet him self and decided to come join despite their fear of my hand.
Due to millet having a high source of fat, I would not recommend giving too much to your birds. It is an excellent treat to use to tame your birds. If your birds never had any, I would recommend leaving a little portion of it for them to taste. Once they taste it they will know that it is candy for them the next time.
This will take some time so please be patient! Hold your hand in the cage every day with some millet on your palm. If you have more than one bird, sooner or later one of them is going to come and nibble your fingers. Stay still till they start eating from your hand.
You will notice when one starts to eat from your hands the others will automatically look interested to and come closer. However this will take some time and the time varies depending on each bird, so be patient!
I think this is an excellent way to tame your parakeets, by using a millet. Any body else with more ideas?
