Hi. I also have a baby Veiled Chameleon who was not eating for a while after he came home. Someone mentioned that he was probably just still too stressed to start eating, I think he eventually got hungry enough to go after the crickets. I too was told that the meal and super worms aren't the best thing for the babies to eat, I guess it can cause blockages?
I don't have any advice since I'm a new chameleon owner myself but I'm sure it's just his nerves. Does he seem to be active and moving around like normal? I would be concerned if he was lethargic. How is his color? I think their color is based upon how they feel or changes depending on heat, humidity, etc. I hope he'll finally get hungry or comfortable enough and get after the crickets! c:
