Alot of times I use the DHL bubble envelopes - their supplies are free. When mailing chicken eggs, I cut a square out of it, and make a little pocket, stick the egg in, and tape it closed. You can also use an egg carton and wrap the whole carton with bubble wrap or foam. Use lots of packing peanuts on all sides of the eggs or I even use pine shavings - anything to support the eggs and keep them from touching. Pine shavings also work good because if an egg does break, the shavings help to absorb the liquid.
Whe mailing quail or button quail eggs, you can do the same as above or use a quail egg tray. The holes are kind of big for button eggs, but I fill any gaps with pine shavings to keep them from moving around, then pack the top of the tray with pine shavings and wrap it with bubble wrap or foam.
Make sure you collect the eggs only a day or two before you mail them, and only send on a Monday, Tuesday or Wednesday so they're not losing time and viability sitting at the post office. Priority mail is the best, but the flat rate boxes aren't always the best choice because depending on where you're sending, it could be cheaper than the flat rate (learned that one the hard way!) You can go online to the USPS website (
www.usps.com) and check out the rates. You'll need the zip code of where you're sending and the weight and measurements of your box.
I've sent a ton of eggs and have never had any break doing it this way. I've received alot of broken eggs, so I've learned what not to do!
