Try making a free range that is high up for her. Put a stick inside the cage to the free range. Do this fairly often. Then start only using the stick to transfer her to the free range, and then after a while of that and her gaining your trust she may eventually come to your hand. Once she trusts you and realized you are the source to her free loading...possibly she may give in

. This is how I did it for mine. He would occasionally get curious and come out, but rarely would he take the step to get on h hand. For a while othe would try to use anything but my hand to get out. Once he realized he couldn't without climbing onto me then he chose my hand, and I would quickly put him on his free range. He literally will almost "run" to grab onto my shoulder while I'm cleaning or up in his cage. And half the time I offer my hand he will freely grab on. Sometimes he will just chill on my shoulder. But once he starts migrating down I know he wnat to explore. So I will take him outside or put him on his free range. You just need to get the chameleon to trust you and realize she can free load off of you . Continue offering feeders by hand. Try leaving the cage door open more and be around her more so she gets use to your presence.
