If you get a small pyrex style glass bowl and affix it somewhere in their enclosure were frogs can reach, only need to place crickets in it. Crickets can't climb out and they don't even try to jump either. That way you can: monitor whose feeding; how much; and end their possibly stressful handling. Works for Dubia roaches too and can feed dusted insects right from it. Some of those bowls have two little handles and the frogs can sit on them while they feed. Good luck !
