Feeding Juvie Bearded Dragon Adult Crickets?

well i feed my juvenile leopard gecko adult crickets and he is only 6in. long form nose to tail tip so i would guess they cant cause any harm i have used adult crickets for years and never had any problems with the leopard gecko and bearded dragons are more hardy any way so i wouldnt even chop them up into smaller pieces i would let him have them whole the only problem is with adult crickets when bout in large stock (like anywhere from 20-50) they eat each other when not correctly fed and can try to take a shot at your lizard when left in the tank
