@Beman Thank you again! Yes, they're in a cricket keeper with tubes. We were just shaking the tubes right into the feeder, which wasn't working too well! The harder part was getting the crickets out of the feeder itself in order to relocate it though. We're learning the hard way with a lot of this.
So, right now, the crickets are sitting perfectly still in the feeder. If we tap on the feeder, they move a bit, but not much. About 12 of them can squeeze into the top edge of it and hide there! Maybe Ellie just needs to use the money she got from returning the waterfall and buy an actual shooting range. ?
