It has been proven that one method of prolonging the hatchability of eggs is to store them pointy side up in an egg carton that has been enclosed in a plastic bag kept in a cool place such as inside a closed cooler. No turning of the eggs is done during the storage phase. Eggs stored in this manner have been shown to have up to 80% hatches after storing for 30 days. Enclosing them in a plastic bag, storing small end up inside of a cooler has been shown to help prevent the loss of air from the air cell.
You should be able to read about this storage method in the hatching eggs storage section in Hatching Eggs 101 by @Sally Sunshine
There has not been any evidence shown that wrapping the eggs tightly in bubble wrap causes any damage. There is evidence to show that allowing the eggs to "spin" when unwrapping the bubble wrap can cause damage.
Other things that cause damage during shipment are being placed in a non-pressurized plane at altitude which can cause the destruction of the internals of the eggs. Flying them in a pressurized area of the plane works well but not in the non-pressurized cargo parts of the planes.
Eggs that have their containers turned upside down can suffer when the small ends are up during the shipping process.
The shipping method with some of the best results is to wrap the eggs in bubble wrap, well packed in a box which is then bubble wrapped inside a larger box. The outer box and bubble wrap help to prevent the vibrations being passed into the inner box and the eggs.
). So many friends, new and old. So many concerts. Plus I’m getting 5 new chickens and am going to have a giant garden this year, which will hopefully help me to eat healthier and lose weight. Though I also have lost a little weight already. Not much but started working out again today.
This semester is really doing me in. I’ve had a constant headache for the past four days. 
Negan with his crowing and Benny with the screams/oinks isn’t helping either. We’ve also got a broody who I’m frustrated by, a 4 dozen hatching order that *might* be completed by Sat. and the stupid band of hawks (8 hawks!!) are basically sitting in our yard all day long. It’s been a week.
some older gentleman asked for 10 dozen eggs today 
That's wonderful, when I was following regularly (before I started working ) Y'all were just getting started selling eggs. It sounds like it is starting to work out really well. 
I am so glad for y'all. hope your headache gets better soon and your current semester gets better and easier as well. Hopefully the hawks will decide to go somewhere else. Sending prayers and good wishes your way 
Let us know how things are going in the future as you have time. LOL
