alright, I'm about to put my first batch of eggs into a brand new incubator i built. I have 2 25w bulbs with a water heater thermostat in between them and a pretty strong fan blowing in there. I just want to know if that fluctuation is ok, 97 degrees up to 102... I want to say it takes about 15 minutes to cycle...what do you guys think?
