Help!!! Need to know how long eggs can survive

[Opiumbrella]

By 19 days the embryos are generating a lot of heat themselves. That was not a good thing to happen but it's probably not a disaster. My story is I had a hen off the eggs long enough for them to become cold to the touch, not sure how long but several hours. She still hatched 11 chicks out of 11 eggs. Those chicks were not delayed either. They still hatched early.

Let us know how it goes.

Two have hatched!!! The rest are pipped. Everyone looks normal and healthy!!!
