I've had to seriously bulk up on crickets with my zoo, yet most of them seem to die before I can feed them to the frogs, toads and geckos. I have them in a 5 gallon plastic storage bin with air holes, paper towel, cricket jelly, natural egg carton hideaways, and am gut loading them with apples, dog food, carrots, kale and calcium. Yet half or more die, and I feed my animals every night. I would really appreciate any suggestions or hear ideas of how other members house and raise their crickets. I have bulk 4 week and 3 week if that matters.
