I purchased 4 eggs from someone on eBay who was in Texas. 2 went rotten, but the other 2 seem to be developing. They’re leaning to the pointed end considerably now.
From my hatching experiences from eBay over the last couple months, yes you can get good eggs. But at the price of possibly losing 50%. The shipping part is what does it. Also, you have no idea if the eggs are any good. If you find a good source, stick with them only.
