Congrats on your wonderful hatch!
I have been lurking on this thread for quite a while. I finally took some pictures of my packing method that I have been using for the past few months. I have been having very good luck with it for the most part. The eggs arrive intact and most have reported good hatching rates, though I haven't kept track of the numbers.(Sometimes the PO does their best to scramble eggs no matter how well they are packed
) Some of the packing materials may vary depending on what I have on hand, as I do recycle, but the basic idea remains the same.
The eggs are wrapped in bubble wrap. Each 12x12 sheet of bubble wrap is cut into six pieces. Each wrapped egg is then placed inside a plastic Easter egg and it is taped. If the egg is too large to use bubble wrap, I just use a piece of paper towel for a little cushioning.
I then line a box with bubble wrap and put in some shredded paper to nestle the Easter eggs in, large end up.
Then I put some more shredded paper around and on top of them and cover with more bubble wrap. Because the eggs are encased in the plastic eggs, I can stack layers if I need to.
This box is sealed and placed into a larger box (I use the Box 7, 12x12x8, from the PO), surrounded by crumpled newspaper.
This box is sealed and I write "Fragile! Live Embryos!" on all sides except the bottom, label it and hope for the best.
My local PO workers are very good and treat me like the very good customer that I am. They are appalled any time I tell them a box has been crushed in transit. They do pass the complaints up the line because they realize the future of the PO and their jobs depend on it. I now add insurance to every package of eggs I send out. Even if I don't recover any money from it, every claim MUST be investigated. This not only costs the PO money, but spotlights problem areas. The more we complain and file insurance claims, the more likely we are to effect a change.
