Veggiegirl- That's pretty much what they're there for. Otherwise, we'd be up to our eyeballs in baby guppies! However, I did give them some extra cover, so they have a little bit of a better chance to make it to adulthood.
Aemaki- My common girls always give me really small drops. There's only 5-6 that I've counted so far. But Mike has 4-5 girls that are about to drop, and so far Georgia holds the record here with 32 gupps in a single litter, and that was right after we got her. She's had a couple of smaller drops since.
