This was my craziest hatch ever! Due Sunday but started hatching Friday and Saturday. Then we had the electrical problem Saturday night and temperature dropped. Had some hatch Sunday. I declared the hatch Sunday evening, but left the eggs in the hatching tray...three more hatched today.Well... I apparently have a problem with the circulation in my FI incubator. I will have to check it out once this batch is done. My first chick hatched out Friday morning at 10:30am (the end of day 19). Two hours into day 23, I have 24 chicks, and still going with a pip, and an active zip.
