The reason why they ARE eating out of a humans hand is because they let their natural instincts and guard down. The reason most times for that is because they are so so hungry they are willing to risk it and get that close. Personally I don't want to put my birds through that, but that is just me.I see all these videos where the birds will eat from their owner's hand. I try to do it all the time with my birds and they don't eat from my hand. Any suggestions?
