I woke up this morning and I had a super low temperature spike in the eggs that could have been for hours. Now I'm running the temperature high, at 100-102 to try and save what I can. So, I'm trying to figure out just how long it takes for the temperature recorded at the egg shell to reach the embryo inside. For example, if you have a spike that's say 105 degrees but it's for 5 minutes, that's probably unlikely to harm anything because the egg hasn't heated to 105 on the inside. Hope you guys get what I mean!
