This might sound cruel, but I'm not really woriied about being overstocked, just as long as they live long enough to be snacks. they are going to be lunch eventually anyways, so as long as they do there thing and make more lunch before they become lunch I'll be happy. Maybe I'll look into a 20 though, if you think that the convicts will breed like rabbits, and only if I don't have to remove them when they breed.
