My husband went out to cut the grass and found a pile of 7 eggs. They're pretty dirty, so it's hard to tell if they are from our chickens or from the wild ducks that enjoy hanging out in our back yard. If they are chicken eggs, they would not be fertile. If they are duck eggs, they would be fertile. The ducks have been mating in our pool. Our back yard is not so large that these would have been sitting there long, probably just 3 days at most. It's been raining, so we haven't gone outside much. What's weird is that the eggs are really light, as if they were empty, but there are no holes or cracks in the eggs. Also, they were found next to the coop and at that location, it looks as though something small had dug under the coop and maybe even pushed these eggs out from under the coop. The chickens cannot fit under the coop. So something would have had to have located and pushed the eggs under there in the first place if that is indeed where they came from. It could just look as if something dug under the coop and it was only the mystery layers who dug up the area. Candling has done little to help solve the mystery. Can eggs dry out over time so they would feel empty? Does a fertile egg with a chick feel the same (weight-wise) as a non-fertile egg? I've never really handled eggs once they had a chick in there. Either momma had them or they were snug in the incubator. I hesitate to crack one open in case it's a fertile duck egg. My son insisted on putting them in the incubator. They've been in overnight and don't stink....yet. Please help solve the mystery if you can. Thanks!
