So I had 26 eggs in my bator. At 25 days I had a hatch of 0%. My bator came with 2 thermometers. I had one of them outside in the brooder and one in the bator. When I put the second one in the bator I realized there was a 7degree difference between the two. Which was right? Were either right? 90% of the eggs were "quitters." So heads up if you buy a Little Giant Incubator do not use the thermometers that come with it.
