Also be mindful that to ship birds or eggs across state lines you need to be inspected by the state and certified NPIP clean flock to be legal.
I have shipped a lot of eggs and the best way I found to ship peacock eggs is to wrap them with tissue and place them in a goose egg carton if you have any. I shipped a lot of turkey eggs this way. If you do not have any goose egg cartons, I would wrap them in bubble wrap around the sides, leaving the top slightly open so they can breathe, but tightly around each egg and put them in a 6x7x7 regional box, using whatever you have to keep them from moving around, like smashed paper, shredded paper, peanuts, like many things come in when bought online, shavings, sawdust, basically anything to protect the eggs from getting knocked together, or touching the sides of the box. If you do not have a regional box, any box that they will fit in after they are wrapped in bubble wrap, most people get from packages they buy in line. If you do not go over 2 pounds including the box, shipping should be $5.00 shipping cost through the mail. That is their minimum rate to ship anything 2 or under. There is a slight chance they may be X-rayed, by the sorting machine, which will check packages at random, because of a homeland security action, but that's only slight. I mark my boxes live eggs, please handle gently, all over the box and ask your post office to put fragile stickers all over the box. They have plenty and are free orange stickers that are extremely noticeable! If the postal employees are efficient, between you and me, they will pull the box off the sorting machine and handle it gently. When I was shipping about 8 boxes of eggs a week to people, only about 1 % were damaged or had the embryo damaged. After I get them, I will let them rest with the air sack up for 8 hours before putting them into the incubator. The connective tissue that holds the yolk in place is very strong and I usually get an 80 to 90% hatch rate on shipped eggs.
