Sometimes no mater how hard you try eggs get broken. I have shipped alot of eggs I rarely have problems. however last week some were broken in shipping. I bublewrapped each egg and placed them big end up in a small priority box that was lined with bubblewrap. then I packed that box within another box with foam peanuts. on chicken eggs they would also be in an egg carton however my duck eggs don't fit in egg cartons. I had sent tons of extra so the receiver was happy.
