We were going to take our incubator with us to the ocean, two hour trip. Eggs on day 18 and starting one is starting to get ready to hatch. Plugged in car power convertor and discovered it is broken. Do we leave them here and hope that the kids will check on temp etc or would the eggs be ok if we wrapped up the bator in blankets and took them with. The drive is almost exactly two hours, would they be ok for that length of time?
