They take 16-18 days to hatch...my last hatch took a full 18 so I didn't figure this would be earlier. But, my new incubator works so smoothly that I guess I shouldn't be surprised. I woke up to one of the 13 pipped! A nice big pip too! Hopefully she'll come quickly and then the others won't be far behind. They hear the first chirping and it calls them. I'll be back with pics.
