One of my good friends was telling me today that he had over 60 eggs due in about a week. he obviously was keeping them in an incubator that he made. There was a storm that night while they were asleep and the power went out. since they were in the basement it was a bit colder than the normal temp in the house. the incubator light and circulation fan went out and was said to be out for about 9 hours. He figured all of the eggs were gone but kept them under the heat anyway. but he ended up losing his batch that he had all prepared and labeled.
