@Sally Sunshine Hi Sally & Mike, I have 4 pips this morning This is suppose to be hatch day, but upon calibrating the therm/hygro in the incubator that they spent the first 18 days in. For some reason the thermo was off a degree. I had calibrated it just at the start of putting those eggs in. I'm not certain why or when it changed but that would explain why these eggs are running late. So glad I checked it before adding another full tray into that incubator. Sally thanks for STRESSING the importance of calibrating before EVERY hatch
