Hey there!
My GCC, Bertie, I bought in May from a (I now realise) awful pet shop in May.
I've worked with him so much in the last few months, giving up all my spare time out of college to him, even missing nights out because I feel mean leaving him.
I spent a lot of frustrating time trying to get him to 'step up' onto my finger, which resulted in a lot of flipping hard bites. Drawing blood every time.
I actually gave up teaching him to step up and became content with him stepping up onto my forearm and getting him to fly to me using stick training (which he picked up on easily) when I couldn't reach.
I slowly got him to trust me and he slowly began to let me scratch his head. It came about as a result of snuggling in bed with him on mornings, and slowly he'd get sleepy enough to let me touch him. That recently led on to stroking his back.
Only two weeks ago he stepped up onto my finger of his own accord to get my fruit juice, and since then he's picked up on 'stepping up' without fail. He still bites me, but only to hold onto my finger in an 'Oi, naff off' fashion. It never hurts and I'm happy to stroke him without looking now.
Last week I flipped him onto his back for the first time and he'll now lie back happily in my hand. He even let me clip his nails without screaming/freaking.
Either Bertie is very lovely, or yes, you can most definitely tame parent raised birds.
