This morning I was focusing on attempting to teach him to step up. He has never done it before and usually bites if you try and touch his feet. Either that, or he just moves away from you.
I read around quite a bit on how to get a parrot to step up, but most of the books i have and tutorials and guides I have read assume that the bird is well mannered enough that you can offer your hand to him. Percy is not

Even the idea of using a hand held perch instead of the hand didn't work as he gets scared of the hand held perch.
I did a bit more research yesterday. And I found a youtube video where this guy was target training his parrot (a biter also) whilst putting his other hand close to the parrot's feet. If the parrot makes a move to bite, he moves away and the parrot does not get a treat. Basically, over many attempts, the parrot starts accepting the hand to be closer and closer. Eventually he shouldn't mind it at all and the next step is the step-up
This morning I got to a stage where Percy wasn't minding my hand close to him that much. So I am hoping that a couple of days of this will get him to step up. Wish me luck
