It depends on how many chams do u have...how old is the cham...what size container do you want to keep the crickets in.
The guidelines for Panther cham example
Neonates: as many small crickets as they can eat several times a day
Juveniles 3-6 months of age: 10-12 small crickets daily
Juveniles 6-12 months of age: 10-12 medium crickets every other day
Adults over 12 months of age: 7-10 medium-large crickets every other day
Put everything together ,that will be your answer.
