So I've had Shu for 2 weeks now and since then she's settled in real well, she's a pretty chill thing and isn't bothered by much which is cool, and we hang out a lot
she likes Radiohead which I can definitely respect haha
First I started putting my hand on the cage bars until she was comfortable enough for me to put my hand inside the cage, and then I worked on hand-feeding her millet which she was happy with as well. I managed to get her comfortable with my finger sitting right next to her and stuck with that for a few days, and today I decided to see if the temptation of millet was enough for her to step on my finger.
Her favourite perch forks off at the end, so I put my finger on one 'prong' while she was sitting on the other and then held out the millet. She started chipping away at it and I gradually brought it forward so she had to lean right forward to get it, and then she put a foot on my finger. I held it like that for a bit and then moved my finger up, and she brought her other foot up so that she was perched on my finger and still going full-bore at the millet
After a bit I moved my hand away from the perch so she'd realize she was actually on my hand, and she was still quite happy with that. She finished the millet and stayed on my hand for a little bit longer and then returned to her original perch.
So all in all I think it went quite well!! I've heard of budgies perching on peoples' fingers and actually being terrified but she willingly stepped on to my finger and went back to chirping away after she'd mowed through all the millet, so hopefully that was the case haha. I won't do too much more for now bc I don't wanna stress her or anything but it was cool to see that she actually did it, even if it was just for the food ahaha
