I would like to order crickets on-line in bulk but I am not sure what size to get. If I order ~500 that should be 1 to 1.5 month worth for him. He eats 1/4" crickets so if I ordered 1/4" crickets will they grow too large after 3 or 4 weeks for him? So I guess the question is, how fast do crickets grow? Do you account for this in your cricket order or just through out any that grow too large?
