Yes, they go crazy over crickets and meal worms and they like red worms but they won't touch anything else. I've tried oatmeal, yogurt, raw peanuts, spinach, boiled egg, cantelope, potatos, tomatos, watermelon, squash and probably a few other things that they have no interest in. Will their taste for different foods/treats develop as they get older? I sure hope so 'cause I can't have any picky eaters around here.
