They'll hate you forevverrr

[Buddy]

I taught Bubbles early on when I first got her that she had to walk onto my hand from her cage if she wanted to come out. And if she wanted to go back inside her cage she'd prop herself up onto my chair and wait for me to put my hand out for her to climb on so I can put her back. Some chins just don't like being picked up, it's not that they don't trust or hate you- some are just harder to tame than others. One thing that does show your chin doesn't really trust you yet or isnt tame is if she/he lets you go near their tale or not. If they don't then just keep at it, soon enough they'll be climbing on to your hand to be picked up
