Ok, this is my first incubation and hatch in my HovaBator 1588. I didn't even have a thermometer in there the first 18 days. I put a Fluker's Thermo/Hygro in there when I took the turner out. The Fluker's registers 95* so I figured I would be a few days late hatching at lower temps but I left things alone just to find out what would happen. Well, today is day 21 and so far I have 3 pips from 12 eggs! I'll keep you posted.
