Okay um..... So Eric&Rebecca's answer was great!
Though I feel the need to comment on the fact that you
actually chained him to the perch? ...Please don't. Ever.
Also, I'm sorry but it really bugs me that you're chasing him with your hand trying to pet him when he doesn't want to. I honestly don't mean to sound harsh, really, but to me it just looks so stressful for him.
I know you're not doing it on purpose, and you probably didn't know that you shouldn't ever chain him to the perch - but I just can't help but cringe.
With that said, I think you should try target training out. Give him lots of treats if he's close to the target stick without being afraid, and soon enough he should hopefully get that it's not as scary as he thinks and you can start with the training.
(I don't know, but maybe even try starting targetting when he's inside the cage? Pretty sure he feels more secure in there since you said he would climb into the cage when you tried touching him before you... Chained him to the playstand? Sorry if I misunderstood something but that doesn't look or sound good at all.)
But yeah, please don't chain him to... Anything. And good luck with training him!
Sorry again if I sounded rude. I mean, the fact that you're asking about him on here shows that you actually care about him and that's awesome, you probably just don't know better.
