It is disappointing when shipped eggs don't hatch. I got 30 eggs from an Ebay ad 15 days ago and the box was partially crushed, smelled like rotten egg, and had a wet spot on one corner. Five broken eggs and the rest with broken air sacs. I put them in the 'bator anyway and a few actually started to develop, but I cannot see an air sac?? Don't know if one can hatch w/o an air sac. A few have blood rings, and the rest with nothing, as I expected. It's looking like I'm not going to get any to hatch out of this scrambled mess. USPS gets a big fat F in this case.
