Well, our last hatch didn't go so well. We had gone by the reading on the digital display on the Reptipro but only 1 chick out of 16 eggs hatched. Come to find out, it was actually about 2 degrees below what was displayed which is why nothing hatched. For this hatch, we put in a digital thermometer/hygrometer that had been appropriately calibrated, and now we are getting more accurate readings of the temp and humidity inside. Obviously it is working better now because we're getting pips! BTW, the little pipper is working on his zip! He has knocked a big chunk of shell out, and some of the other eggs are rocking around in there.
We also have the egg turners but took them out for this hatch and are trying something new. We just laid the eggs on their sides, whereas before they had been in cut-down egg carton trays. It just looked like the chicks were having such a hard time pushing their way out of the shells with the egg sitting upright, and the one that knocked themselves over on their sides seemed to have an easier time hatching, so we just did the whole incubation on their sides this time.
We also have an LG 10200 incubator with forced air, no turner. *Love* that thing and have had excellent hatches in that unit. We are really good about manually turning our eggs, though, because I work from home and am here all day.
