There is another breeder in my state, but our entire state is in the double negatives for the next week.
Temperature aside, if possible, make the drive to get the eggs. Better than the mail where packages are just another object and are not cared for.
Eggs can take quite a bit of abuse before the air cell is broken or the egg is scrambled. When my family moved here, TN, from WI we had a broody in the van brooding eggs. It was not an easy drive. We stopped at relatives, got lost, had a near accident, and drove through severe storms. At one point we hit a bump and everything in the car was tossed around. One egg was lost. After arriving in TN and our new home the hen hatched all the remaining eggs. Makes a person wonder what the post office does that ruins so many shipped eggs.
