That big egg auction that I did this spring was shipped that way. She ended up getting 12 dozen silkie & faverolle eggs, 16 peafowl eggs, and 6 african goose eggs. They went in 2 separate shipments about a week and a half apart. A few dozen out of the first batch were even forwarded on to a friend of hers. She reported back 68-71% fertility. That was right about the same as I was getting here. It cost right about $160 to ship both boxfulls. Eggs and tons of packing material are not light and thus the express mail goes through the roof. I just sent her another 4 dozen eggs about a month ago and nowhere close to the same results. If you are willing to fork out the money, they are definitely taken better care of in terms of fast service, getting jostled around, climate controlled etc. If you want to see the results, go check out Anh's pics (Dylan's Silkies). She got some beautiful babies out of it!
