Hi there! I am wondering what kind of thermometers you all use for incubation. I had been using the one that came with the incubator (think it's Mercury) I tried to calibrate it as well as I good, it just had the cardboard backing to adjust. Then it was recommended that I get a Brinsea Spot Check. Well, since using that, and keeping it at 99.5 many of my eggs seem to be dying! When compared to the one that came with the incubator, it reads higher. Brinsea 99.5 and the other in the low 90's. Not sure if it very accurate! The reason I switched is because it seemed like my eggs were trying to pip to early.
