James, I'd go with the crickets for now. If their food item is too big they'll try one, spit it out and then not go for another. Also check for poop...if they're pooping they're eating. Remember when I said I kept my baby's setup real simple with a paper towel and one plant? The reason I did that was that it was very simple for them to see the food but it was also easy for me to check and see the next day how many crickets were left and how many poops I had.
