Some ideas
Chams change colors to reflect thier moods. Notice, that when your cham is left alone and you have just come home, and he is all mellow, what does his color look like. Its probably kinda light brownish. When he is excited and afraid, what color is he?
Now look at yourself. You change colors every day too. Sometimes you wear a red shirt, and other days maybe a green and yellow striped shirt, or maybe light brown or grey. What color you wear around your cham will effect its perception of you, at that time. Keep it to browns, light green or even grey, and that will help mellow the mood.
Birds approach prey (chams) from above. Try to never approach your friend from above. Also, try to avoid any grabbing, like abig mouth/hand biting him. I come up from underneith mine. She moves to avoid me, but I just bring my other hand into her path from below, and before we know it, I have a cham on my hand. Be careful here!! I almost injured my chams tail because I pulled away as soon as the cham was on my hand. The tail was still wrapped firmly around a limb. I felt the tug and the limb bent a little, and I fealt horrable, but the cham was fine.
Other people bate their chams with mealworms resting in the crux of the elbow just out of toung reach. The cham has to get onto your hand to get the goodie.
Dusting and releasing the hoppers is not horrably bad, but there could be problems. If the cham does not eat all of those hoppers, they could step into his poop and then later when the cham does eat one the cham eats its own poop and bacteria, parisites.
Are your lights inside or outside the enclosure? If inside, they should be placed outside, or covered completely in mesh so the cham cant get a burn. Its not enough to cover the light bulbs. You have to cover any and all hot surfaces!! If you cant grab it with your hand (because its too hot for you to touch), its too hot and needs to be covered to protect the cham.
Many people on this site are dead set against any unnecessary handling of chams, but I disagree with that. That said, I do not advocate taking your cham out for drives on saturdays either.
