There is no way I would ship eggs. Mainly because I do a lot of selling on EBay and I do my best to avoid negative feedback, and being a retired postal employee,; I know how they are handled. The mail moves locally between post offices mainly by private contractors in box-trucks that have no heat in the winter and are oven-hot in the summer. I have seen several mail cages of live quail that were already on the truck when it arrived at my location, and had over two hours more before they would be transferred to another box-truck before they would reach the distribution center in KCMO. But usually live chicks in the spring and fall have good survival rates.
I agree Ralph I really don't want to ship them either. I have been asked to sell hatching eggs & ship them & I would just rather not because I know how the outcome would most likely be. Even the people who pack as carefully as you can pack still have issues just because of the handling. There are certain places I have found are better to get my eggs from because of less hubs they have to go through, less time, & less handling.
