If you already have an extensive system, and it’s time for your snails to breed, you may find that you need to add an intensive element for hatching and rearing young snails. If you already have an intensive system housing eggs and baby snails, you may discover that you need to add an extensive component as your snails get larger and need more space. Add to it as your snail population increases. Overcrowding can cause snail growth to lag and can encourage the spread of disease among your snail population. Typically, you want about 1 square meter for every 100 hatchlings and about 1 square meter for every 7-10 adult snails. About once every two weeks, take the snails out and replace the old compost with fresh. Be sure to also remove any pieces of rotten food at this time. You will need to do this with both extensive and intensive systems.  Be careful of moving baby snails. Adult snail shells are hard enough that you can pick them up, but try to move baby snails by nudging them onto a stiff piece of paper and transferring them gently. Use shallow dishes such as jar lids or  yogurt container tops to prevent snails from falling into the water.  If the water starts to look dirty or gets a lot of food or droppings in it, replace it immediately.
