Well, I have my answer. Asked earlier if anyone thought they would hatch after no power for 13 hrs. I woke up this morning to 5 of the 15 already hatched! Even if no more hatch im glad at least some of them were saved.
Congratulations on your hatch! Unless temperatures drop significantly for relatively long periods of time, power outages generally do nothing more than extend the hatch period. Best wishes for a good hatch.
