They probably won't hatch because they haven't been fertilised. They will make good fish food though.

Keep any eye on the eggs. I don't know how long you have had the snail, but the females can store sperm untill they want to lay eggs. Ramshorn snails can be very prolific. The golden snails that lay eggs above the waterline are apple snails. you do need to bring those into your aquarium in winter or they will die. If you take good care of them they can live for about two years. Applesnails reproduce by sexual reproduction, and can lay multiple clutches from one copulation. One could be fertle while another might not be. Once they hatch the babies are so tiny that you can barely see them, and if you have big fish in your pond they were probably eaten, before you even knew that they hatched. If you get more snails for your pond next year, when they lay eggs, wait for the clutch to harden ( about 4 days) then scoop them up. Roll the clutch up in a dry paper towel, place it in a ziplock bag with a damp paper towel that is rolled up in a dry one. (the eggs need humidity, but will drown if they get too wet)seal and float the bag on top of the water in your aquarium, after a few weeks of keeping an eye on it the babies should hatch. Keeping them in a breeder net is the best way to make sure that they don't get eaten. After about two weeks the babies should be about the size of a BB. It will probably be safe to let them browse around your aquarium. I hope this helps! Thought this might be usefull info since it seems like you want to be a snail mommy!
