Our happy chickens lay healthy eggs!

Depending on the time of year, here are examples of how I wrap up hatching eggs and ship them out.
Guarantee...... there is no guarantee that your eggs will hatch once they have gone through the PO. Please realize when you buy hatching eggs it is a gamble due to shipping and your own incubator. Viable eggs can leave the farm and arrive at your home in a non-viable state. Just because other eggs in the incubator hatched, even shipped from someone else, doesn't mean all the eggs will as it depends on the handling of that particular box during shipping. Your eggs may not hatch. Because of factors related to shipping, a fertile and viable egg can be shipped to you and arrive in a nonviable state. When candling the eggs, nonviable eggs appear clear, just as infertile eggs do.
I wrap each egg, pack inside bubble wrap or shavings filled box and write Fragile- Live Hatching Eggs on the outside of the box to alert the post office to its contents.
Due to the time sensitive nature of the eggs, I want to get them to you as soon as possible. I ship them Priority mail and put insurance on them in case of a problem while in shipment. Once the eggs leave my hands I am not responsible for their handling. I do not guarantee hatch rates. As with all shipped eggs, hatch rates are variable and not within my control.
I do guarantee that the eggs are fresh, within 4 days of shipping and they are fertile since I also set from the pens every week. I guarantee that the eggs are from the proper pens noted on the eggs and are the eggs specifically ordered. I do not make up some obscure code but I do write the rooster's name on the eggs so you know which pen it is from.

Disclaimer: by purchasing these eggs it is understood by the buyer the risk of hatching eggs and the seller is no longer responsible for eggs once they leave the address of origin.

I did not ship out eggs in this but this is an example of one of the many boxes I have used to ship items. This box actually works great for my peacock feathers to be shipped out in since it is very long.
In the summer, I wrap eggs in thick paper towels and put in an egg carton, where I bundle all the soft paper around them before closing up the box.
I tape the carton closed on the end and side to keep it steady during shipment and so the new owner can handle it safely when unwrapping it.
If cool enough outside I will wrap the carton in bubble wrap but if it is too warm, over 80 degrees, then I use shredded paper or shavings so the carton rides well inside the box.
I ship Priority mail but will also do Express or Fed Ex if buyer asks. In order for the PO to recognize the value of the box being shipped and insured, I make sure to write Live Hatching Eggs on the box along with Fragile.
Here is another example of how I ship eggs when the weather is much cooler.
I do not think you can get too much soft material around the eggs but there can be too little.
I do try to make sure there is plenty of material around the inside, top and bottom of the box so eggs are snug and well protected. This photo is just an example.
Please note that while I ensure the nesting boxes have clean shavings and eggs I send are the cleanest possible, there may be dirt smudges on them. My birds live outside, not in cages up off the ground. Their feet get dirty and they often transfer this dirt or mud to the nestbox or eggs. I set the worst eggs myself and get great hatches. I never wash eggs nor will I ever wash them before I set them. Nature isn't set up that way. If you do not want dirt smudged eggs then please do not order from me.
Shipping out birds? States require NPIP clean birds be shipped. The PO does ship these live animals Express and they usually arrive within 24 to 48 hours.
Always be sure to put plenty of wet food in the box for traveling birds. Grains, hay or other dry foods only make them more thirsty so foods like melon, apples, peas etc are good for them to nibble on during the trip. It keeps them hydrated and keeps their sugar level up so they can handle the stress of the adventure.
A nice layer of shavings helps absorb some of the shock of bumping along, as well as absorbing their feces and in cooler months helps to keep them a bit warmer.
When putting a box together make sure the bottom of the box has plenty of tape across it to hold the weight of the birds, shavings and food.
As if the PO doesn't know this is an Express delivery, it is best to make sure it catches the eye. Zip ties at the corner of the 2 top sides help hold the box closed. All shipping boxes are supposed to have filters over the openings to protect workers and probably the birds.
Make sure to put plenty of tape across the top where the flaps fold in, on each side of the handle holes so they do not rip out and around the top to hold everything. Just make sure not to tape over any air holes.
Affix the address label, using clear tape over the entire label to ensure if it gets wet the info is not lost. However, writing the telephone number on the box on both sides can greatly help, too. Make sure there aren't any wrinkles in the tape over the barcode or the PO scanners have a hard time reading it.
Shipping one dz eggs usually costs $12 to $15 to most zip codes. In the price of shipping you also have the cost of packing materials and gas to run it all the way to the PO.
Shipping of birds depends on weight of box with birds and zip code to zip code. Some breeders will set a flat rate and others go by exact cost for them.
