I feed my crickets store bought gutloading food and mix in crushed fish flakes, cat food and powdered milk. As well, I give them several carrots and leafy greens throughout the week. If you are confident that the crickets are gutloaded to your satisfaction, then I am sure they would be fine. Personally, giving my crickets that little extra has resulted in some fat and healthy frogs-and some very content crickets before they become frog poop!
