[QUOTE="megalomaniac, post: 5890622, member: 2805"] totally not an issue. During laying, while hens are visiting the nest only once a day for 30m or so, they eggs can get down to 25 degrees or so for short periods of time without freezing completely. If any eggs freeze and crack, they will just kick them out of the nest and continue laying until they hit their magic 10-14 number to start setting. Once they start setting at 99.7 degrees to incubate, the eggs can cool down once or twice a day for a couple/ three hours with no ill effects (other than it delays development and may prolong total incubation time) during the first 14 days of incubation. The time off nest becomes more important during the 3rd week of incubation, but daytime temps have increased by then. By the 4th week of incubation, they will not tolerate much cooling, and the hen won't even leave the nest for that entire week to feed or drink. They even quit rotating the eggs the last 3-4 days to allow the poults to orient themselves within the egg so their beak faces the internal air pocket on the large end of the egg. And what's even more impressive, the hen instinctively knows how long she can be off the nest based on ambient air temps without the poults dying within the egg. [/QUOTE]
