I have spent lots and lots of $$$ on shipped eggs, and have come to some conclusions: The fresher the egg, the better it ships. The higher quality the egg white (albumin/protein) the thicker it will be, therefore it will protect the yolk better. Also, a couple extra bucks spent on the bigger box, makes a huge difference. I think the larger box is not 'tossed' quite as much. Newspaper has NO cushioning properties. The best way to package shipping eggs seems to be a bubble-wrap or styrfoam in a small box, well padded in a larger box, so there is a big cushion/buffer between boxes. I just set 12 eggs from "Bargain" on here and had 11 develop and the air sacs were all intact, not displaced too much. I got 7 live chicks, with 5 not pipping, but completely formed. She knows how to pack eggs well. I have heard that increasing the protein in the breeding flock will help this problem of quitting at point of pip. I will try this out myself on my breeding flock. I am considering adding some kind of weight to the box, making it have to be lifted, not so light it is just tossed around. The price on shipping is the same for a flat rate box, up to a certain weight. Someone should write a sticky article on "how to ship eggs" after compiling advice from all the posts? I wonder if cushioning with gel packs might work, adding some heft to the larger box, bubble wrapping the inner box? It is not always the post offices fault, but being rude is never acceptable. If we can get shipping eggs down pat, think of how much we can improve of flocks. I don't think getting 3 of 12 eggs to hatch is good flock improvement at all, but it just might be one thing that allows the fittest to survive. I am still amazed that anyone would even bid on less than a dozen eggs at a time with those odds. HenZ
