Results: These eggs were in the ground for at least 3 days, and possibly 5 days in 20 degree temperatures. One egg was partially exposed above ground. I was very doubtful that they would make it, but 5 babies hatched. It appears that two eggs are bad, but they are still cooking. If I had to guess, one of those eggs was the one exposed. This was still a very cool data point for my future concerns about laying in January and February. I won't be as concerned as I used to be, although I stil want to find clutches as soon as possible.
