Bit of a weird one
but I've been trusted to look after a bearded dragon whilst the owners are away. He's very fussy and only eats live crickets, which is fine, but the cage is a slidey door and I don't know how to get the crickets out of their Tupperware box and into the cage without A) releasing them all at once B) letting them loose all over the house!
They were supposed to show me how, but haven't and now I'm scared of messing it up! I'm not squeamish but I can see myself getting all flustered 
Does anybody have advice?
