Thank you for taking the time Carlos. I know it is down to them now, and she will need to decide to eat or not I guess. I can't find night crawlers on any of the livefood websites I usually use, so I will have to look again for those (do they possibly have another name?), but I have found and ordered the Repta Boost and that looks great! I didn't even know these things existed, and I posted on a couple other forums, but nobody even replied to me, I guess because they were common frogs, not exotics, but I feel the combination of these things could save these frogs, especially the 3 healthier ones. I have learnt a lot (even un-useful things like frogs don't digest cricket heads!) and when the time comes, I feel more confident with an exotic. I will keep to the brown crickets from now on. Is it OK to just release the calci worms in a local field, or should I dispose of them somehow?
