I stabilized my incubator (hova-bater 1588) at 99.6 degrees of 48 hour before putting the 42 eggs in it yesterday. For some reason the temp is climbing and I can't stop it. It is now at 101 degrees. I have read that 102 is the desired temp for still air incubators, my incubator is a forced air type and the recommended temp for it is around 99.5. I don't know why the temp is climbing like this. I incubated 20 eggs last month and the temp never went higher then 99.9. Should I be worried at this and what could be causing this?
