^^^ that dos sound good. how i do it is i feed them from a cup. like a tupperware one with all their crix in it and let them see them. then they eat from it after a while them move to the hand.
but your way may be faster than mine lol
In my experience with my first girl I would just take it easy and kind of ignore (seem to not be interested in the cham) form a couple weeks (let them acclimate to the new home. Then start trying to interact with your cham. I would offer a wax, Phoenix, or silkworm off your hand. Don't watch your cham they move very quick lol and it makes them more comfy. Do you like being stared at?? If he seems uninterested don't force it upon him and just cup feed ( however your method) and try another day. But I've learned not watching them def helps. Also fridge the crix your goin to feed for about 5 mins and they will slow Down, if that's the onthy feeders you have but chams do like variety
