Foooood & Treeaaattss!

Thats what usualy helps lol!

Put your hand infront of your bird then show it some treats from your other hand, your bird should then climb onto your hand (While you show him the treats and saying ''step up'') and then you finaly give the bird a treat & of course congratz your bird with ''Your such a good bird''!

After some practice your bird should get used to you saying step up, then hopefuly with time and care it will learn to step up when you ask it too.
