a few years ago i brought a male harris of a guy ,won't mention names.. this bird was 7mths old,nutty as afruit cake,and would not eat from glove ,would hang from glove alot,so to cut along story short.first i'd just leave food at his feet of the bow,which he took ok,and day by day i use to open the door bit by bit with me close by,final the door was wide open,and i'd get closer and closer to him till the time ,then i moved him to the lawn and did same thing,finally after about 2 weeks i tryed on the fist,he didn't eat straight away,but by the end of that day he fed off the glove it is worth
