This is my third attempt at the incubator. I think the first two times we had a HUGE flux in temp. It was steady for two days before moving the eggs over, but since I had to keep opening and closing the lid in order to rotate...constant change in temps. I now have 36 eggs in the incubator. Eggs from the fridge, from outside and from under broody hens (I left all the ones with development in similar stages under the hens). In the middle of the incubator (closest to the heating element), the temp reads 103.3. The thermometer reads approx. .5* to 1*F higher than actual temp. I have placed no eggs in the row closest to the heating element. The rest of the incubator runs anywhere from 101.1 to 101.7. So far, so good. Just hoping that this time works out for me. I've been keeping a tab on the temp and will put a hygrometer in there later today once the temp settles.
