I wasn't excited because I didn't want to set myself up for disappointment, since this was my first hatch, all the eggs had broken air cells and a bunch stopped developing at 8-10 days, including one rotten one. But they're in lockdown...today is day 20. And an egg is not where I left it. I moved all my eggs so I can see them through the window. And I checked and one had rolled away from the others. It could be nothing. Maybe the grate is sloped, or I bumped it...but I doubt it. So, now I'm excited because I have a glimmer of hope.
