hey Dudeman,
here is what I have done for Splat...
right from day one, I started to sit on the floor still as can be about 15 feet away from the cage.
each week I moved closer buy 2 or 3 feet.
within a few weeks I sat right ontop of the cage and all this made him realise it was safe to stay out of hiding.
I started to hand feed right away. in a scooper that I use to get my crickets out of thier tank or with my fingers.
I stayed low, well bellow his head, outstreached my had slowly toward him and keeped the food between my eyes and his head.
at least one cricket per feeding was hand fed to have him get used to me as the food guy.
again, stay low, and move ultra slow.
in time they will get used to thier feeding scoopers/cups...right now Splat will see me walking from 20 feet away with his dusting cup and get ready for food.
start with this and in time he/she will trust you more.
feel free to PM me in a month or two for more tips.
you'll see that in time you'll gain the trust of your cham, it just takes alot of time and learning how to move slowly or sit still and not scratch your nose.
