Hello
@Bro Bott just having the experience from one male veil chameleon, I can say: they do not care about you

️ Our chameleon was in his terrarium without any issues for weeks. After shedding he became an explorer and walking around. With his new skin, it was like we have a new chameleon.
We hand feed him from the beginning and we hadn't a big issue here, but we also agreed to never "grab" him (if it's not an emergency) to take him out. But it's ok to bribe him

️ What worked for us is that when he got a wax worm, we put the worm in a way, that he has to walk over our hands to get it (never grabbing him then). After a few weeks he started to look around and after his morning and noon basking, he leaves the terrarium (we let the door open, when we were around) and climb on the tree directly beside. To get him back was another issue.
In many cases he walked back by himself and we supported him coming over the gap between terrarium and tree (why using the easy way with vines and sticks we built, when you can go the risky way

️). Again never grab, always be the bridge he can walk on but does not have to.
When he is staying on the tree we wanted him back at least one hour before the lights go out so he can do some final warming up, we also don't want him more than 2h outside. At the beginning we bribed him with insects, but probably it's not the best idea too feed close to sleeping time. What we try is to be part of the tree.
Means, we put the hand a bit lower but in front of him and try to anticipate his next steps and get him put one foot at our hand and then nudging him to go fully on top (raising slowly the hand so he does the next steps and is fully at the hand). Always have the hand lower than his height.
The last days we started to become accepted as a climbing spot. He started to explore more (going down in the terrarium to the bottom and also climbing down the tree outside). Good thing we had him outside only when we're watching him.
Anyways, he had never a bad experience with out hands by grabbing or something like that, it's more like a feeder and support for climbing. When he now is climbing and sees the hand, it's ok to use it. Most of the time we either put him back on top of the tree or back in his terrarium. Today he climbed on top of me, having his relaxing colours and observing how I offered him a path back to his basking spot, so yeah....animals never do what you think they should do as a proper animal. He stayed on me for some time, relaxing, while I was working, observing the world. When he started to move down, I went to the terrarium and he went back in. As I said, official accepted tree.
So long story short:
- feed always with your hand
- never grab
- never force and give bad experiences with the hand
- give the special treats (not every day) in a way that he walks on the hand and
- give him anytime the chance to leave your hand
Probably it's different from chameleon to chameleon, but that worked for us.
