haven't tried this yet, but I've read threads about people incubating in the egg cartons from day one. They would elevate one end of the carton and rotate and do the other end the next time for turning.
This is a slight problem in a homemade bator with a lightbulb as the heat source. I did originally put half of my eggs in the Fridge-a-Bator in a carton in order to make it faster to hand turn, however, I abandoned the idea within a few days. The eggs that were higher were also hotter, too hot, in fact, when the eggs on the floor or at the bottom of the carton were at a satisfactory temp. I removed them and placed them on their sides and the problem was solved since then, they were all at the same level. If a heat element were used that distributed the heat more evenly over the eggs, that would not be an issue. My DH resisted the carton hatching method strongly, so we just hatched this last batch on their sides, as we usually do.
Kim, I know of two instances where eggs pipped low, were not noticed and the chicks died because they could not get out of the egg due to it being in the cartons. That would probably not be a large percentage of the total hatched, but it has happened.
