we order our dish from Rainbowmealworms out here in CA they are disposable plastic with a clear plastic ring, some of the crickets do escape but if you put a carrot at the bottom of your babies enclosure that should distract the cricket and it will not bother your Chameleon
leave your babies food in a dish when she is ready she'll go after them, make sure you are dusting with calcium, the new move could have been stressful
