Finally, a large milestone between me and Koki(I renamed him)! He now steps up willingly, and everytime I go near the cage, he goes to the center of his perch, which is where I feed him treats. Now that he will step up willingly, I do not exactly know how to progress without losing the bond that we now have.
He also seems clumsy, since he will lose his balance many times on perches and on my hand, and he is obviously not used to flying, since he was clipped since I bought him. He also had a feather problem; a few of his tail feathers were "suspicious-looking', but now they are starting to break off. I don't know if he's sick, or if he's just molting. In terms of training, I would like to know how to introduce him to getting scratched, and also how to get him used to being outside (I'm too scared to take him outside his cage right now because he might not go back in, and I might have to force him in). Sorry for the amount of questions asked, but I'm just so excited and don't know how to progress!
