I'm not an expert on snails but I will share with you what I know from school 20 years ago. First off, snails breed like mad. There is no such thing as breeding pair. There is no male and no female. Snails are asexual, meaning they have both male and female parts which makes them hermaphrodites. You put two together of the same species and you will most definitely have offspring. Like I said, they breed like crazy. Soon enough you will have more snails than what you know to do with them. Start giving some away and try to only have one at a time if you don't want to deal with the 100 soon. I'm not sure on what to do with the transfering of the eggs. maybe someone else will chime in and help you out. Good look with the babies!
