Heliciculture/Cannibalism by Hatchlings
The first snails to hatch eat the shells of their eggs. This gives them needed calcium for their shells. They may then begin eating unhatched eggs. If the snail eggs are kept at the optimum temperature, 68 F (for some varieties), and if none of the eggs lose moisture, most eggs will hatch within 1 to 3 days of each other. Cannibalism also will be low. If hatching extends over a longer period, cannibalism may increase. Some eggs eaten are eggs that were not fertile or did not develop properly, but sometimes, properly developing embryos might be eaten. A high density of "clutches" of egg masses increases the rate of cannibalism, as other nearby egg masses are more likely to be found and eaten. Snail egg has 12 to 20 times the protein of salad. The protein helps the baby snails start developing quickly and be healthier. Snail egg is an excellent starter food for newly hatched snails, but they tend to only eat eggs of their own species.
