I don't know how many exactly but I would guess around 25 or something. I get kinda jittery around crickets so sometimes I freak out when putting them in and accidentally shake too many into his cage.
I just got my chameleon a few days ago and am very new to this whole process. Me and my mom struggle to put the right amount of crickets in his cage, usually putting way too many! I know he eats them at his own pace but should I be worried about all the crickets in his cage all at once?
