Hmmm...how old are they? Length from tip of snout to tip of tail? Housed separately?
I personally wouldn't go with supers if they're babies. Butters are WONDERFUL! We have a dubia roach colony...very healthy, much more nutritious than crickets, they're quiet, no smell, low maintenance, and can't escape the appropriate feeding bowl (though clearly they like be hand fed) but also won't escape their tub. My hubby hand feeds the dubia and butters are honestly the only other live feeder he will eat. Silkworms are great, calci/repti/Phoenix worms are great but don't get very large before becoming those pesky flies.
You'd save SO much money ordering online as well. I hope you go that route. Batman's favorite has always been his dubia. Basically never looked back
