I get 100 crickets at a time because the shop I use has a punch card system making it necessary to get 100 at a time. I have a cricket keeper that is supposed to support 120-135 crickets at a time, but there seem to be a lot of dead crickets in the enclosure after a night or two. On the average, how many crickets of 100 will you lose when you stock up? I keep the cricket keeper in a deep plastic enclosure because no matter how tightly buttoned up that thing is, there seem to be 4 escapees every night! I don't know how they do it, but they sure do get out. Of course the escapees become the food of the day that morning I find them out of the keeper.
