Happychickenwith10, I'm in the same boat as you are. These eggs didn't go as far as some I've hatched but they had a rough ride. I'm on day 18 and wondering if any will hatch. There is movement in four but they have the worst air cells I've ever seen. Don't even know how the chick has room to develop. I'm anxious to see how yours do. Didn't see the link to the air cell discussion??
