If temps are stabalized, I plan to start the "experiment" with a set of eggs this afternoon. How many of you hatchers, stack eggs? If so, care to share your method, and what your results have been? My incubator has capacity for 28 eggs placed in cartons. I have about 2 degrees temp variation between warm and cool spots (using a fan) but temps cycle within the accepted parameters, so I rotate the cartons through the temp zones every time I tilt them. My thought is to set about 6 extra eggs, so that when I cull any quitters around day 10, I should end up with a full "load".
