I'm borrowing a FI from my neighbor, giving it back today, thermos 2 at mid egg level 1 on top, its forced air with turnedLiz, quite often the storebought ones have temp swings and bad thermostats. You have a FI, correct? Those are so-so. Not terrible and not stellar. I think you will have improved hatch rates if you build a DIY!
Oh! I wanted to ask. What thermo did you use, and how high up on the egg?
