It is one heck of a learning experience with snails, and I am still learning. I have hatched many a clutch and don't have a single snail out of the bunch that has grown to the size that you have in your pics Holly. Congrats to you.
Add RCS to the mix, and you could possibly go mad. I have seen 3 berried RCS but have yet to see any babies in the tank. I put 30 RCS in the tank initially, and if I see 10 at a time it is a miracle. On top of that, I have only ever seen 5 to 10 of them in red. The rest are all pretty clear and I have absolutely no idea what I am doing wrong because the water parameters are exactly how they like them according to everything I have read.
