How do I know..

I have 2 feeder cups in my 2 month old chams tank. One with worms, one with crickets. To ensure my cham can get out of the cricket tub I have a small piece of egg carton in it and the crickets manage to hop out.
She is not eating butter worms, baby meal worms, silk worms, or some weird flat worms the breeder sold me.
I cant keep track of the crickets she is eating and I only have seen her eat one, that was on Sunday, the day after I got her.
How do I know that she is eating and healthy? I can see her ribs but she looks okay.
