I've bought a lot of eggs that way, and also sell on Ebay. After a while you can get an eye for who you don't want to buy from! Worst hatch ever was 0% development on Blue Orpingtons. Best hatches on shipped eggs were from BYC members; turkeys from corancher (100% development 75% hatch) and hinkjc (100% development each time, 80% hatch first time, second time is tomorrow!). Some breeds and species take shipping a lot harder than others. I've had some buyers report 100% hatch
