I'm going to have to try that with the next batch of shipped eggs. I've always thought that 8-12 was the way to go, but I'm up for new ideas! I'd like to use cartons to hatch, (I hate watching the new chicks punting the pips all over while they're getting their legs under them!), but I was always concerned that they'd have trouble climbing out of the upright egg. Is this not as big an issue as I'm making it out to be?
