I say leave em in. Provide them with some food and a source of moisture (or both with some apple or some other piece of fruit) Chances are your beardies will pick em off as snacks and the few that grow up a little more will still be....snacks.
If you are worried about not being able to dust them then just use that cricket gel that has calcium in it and for the most part...problem solved. At least that's my opinion. I have extra crickets in my terrariums that seem to love to hide and eat what food I leave in the terrarium for the misc little buggies that live at the bottom(millipedes,springtails,redworms,waxworms. Talk about an ecosystem going. More often I am cleaning them out of the waterfalls when they decide to go for a swim without realizing they CAN'T swim and don't use the rocks I leave in there for them to get out. I've even had a batch of crickets hatch inside the terrariums without my trying and there was NO way I was going to go after the little buggers....but the anoles and tree frogs loved em.
Just my opinion.
