I used the too temps gages you are using now plus 1 other and the were all a lil off but i went by the white one provided with the incubator and 81 days later at 83-84 degrees i now have 16 pretty babies. I also had problems at the begining cause i started out with a homade incubator and had too much humidity and my eggs got wet but still made it through once i got my havobator a week later so im sure your eggs will make it
