Hey, I have read the popular articles but I am still confused about ventilation. Im at day 3 of incubation and my temp is starting to climb a little bit. It is at 100.8 right now and seems to be slowly climbing. Are the vent plugs for relieving humidity or are they for reducing temps when the eggs begin to emit heat of their own? Should I start venting a little bit or should I just adjust the temp on the thermostat to get it at 99.5 - 100.0?????? PLEASE HELP A BEGINNER! OH, I have a hovabator 1602n with a fan if that matters.
