I was thinking of putting a heating pad in a cooler in a cooler and topping the cooler with a blanket. I was thinking I would have to elevate the eggs off the heating pad by leaving them in cartons and putting a 2×4 under it to turn and elevate it. What do you think? I have some eggs the were dirty and didn't fit into my incubator that I'd like to hatch. The eggs will just sit there if I can't figure out what to do with them.
