My display is sitting on 103. I had to go look since I have never paid any attention to the display temp. I don't trust any of the electronic displays since I don't know (or care) where it is measuring from. I measure the temps on the shelves and and go from there. I rotate them if I have more than one level in at a time since there is a 1 to 1.5 difference. It's all about working out what works for you and your area.
lol.. i use the upper shelf for incubation.. then lower the eggs to the next shelf for hatch.. prefect drop in temp which is just what they need!
