Hi everyone -- Day 7 today. Eggs are looking good. I'm planning to take some to school tomorrow to candle with my son's class I'm experimenting with a little cooler with a hot water bottle in the bottom of it and setting a styrofoam egg carton on top of that & padding it with towels. I'm working on getting the temp of the water right to get a good temp inside the carton. Anyone have any ideas or experience with improvising an incubator for an hour?
