@Bluechick2u : Sorry to hear about your husband's twisted ankle. Hope he's doing better today.
Even with perfect packaging, you can end up with broken air cells and scrambled eggs if postal service employees handle your package like gorillas or allow the automated equipment to rough-up your package. The good thing though is that this is a good time of year to ship because package volume is relatively light (although maybe not so much temperaturewise if it's a long, cross-country trip).
The worst time of year to ship hatching eggs is between Thanksgiving and the new year. Fortunately, not a lot of hatching eggs are shipped that time of year. Many years ago I worked at UPS as a boxline sorter, and during the holiday period package volume would get so high that we didn't have enough available employees to keep up with it. The result would be that packages would get crushed on the coveyor belts and slides. When that happened we used to call it the "meat grinder." It was sad to see. We had people working whose only job was to process damages and to re-tape and repackage packages that had broken open. Anyway, one of the worst damages that I had to deal with was when a 5-gallon container of bull semen broke open on the conveyor and rolled down the slide. That stuff got everywhere, on everything, and on just about everyone. You can just imagine! Talk about gumming up the operation! Yuck! Although I never had to deal with broken-open, shipped eggs; I'm sure that wouldn't have been fun either.
Good luck on your bidding.
