What if days 19-20-21 continued just like days 1-18 while incubating eggs that were being turned automatically by the incubator? My eggs are turned very slowly by my round, eight-sectioned, HTI20 Brower, and the directions say stop it from turning and begin removing plugs depending on the amount of condensation that begins when the chicks start hatching. When I hatched some last time they were all on or after day 21. So why can't eggs continue to turn the last three days (or more for that matter)? Edit: BTW, once there's a first chick hatched, it starts walking around knocking the other eggs all over the place, causing them to move a LOT more than what the incubator does.
