I moved your post to give you your own thread.

As long as they don't look like they are getting skinny they are probably fine. Mine will commonly go right back to the exact same spot day after day and if I didn't see them awake the night before I would swear that they didn't move. I have a little trick that I use. I place a small glass candy bowl in the corner of the enclosure hidden by some plants. I drop in the crickets from the other side just after the lights go out for the night. As the crickets mill around they get eaten by the frogs. The ones that survive always find their way to the dish and fall in and can't get out. The frogs know where to get an easy snack and the next day I empty the dish of crickets back into my cricket bin for re-gutloading. It also helps keep the crickets from bothering the frogs while they are sleeping.
