I have been shipping hatching eggs for the last few month, and have had great luck with keeping all eggs safe. I know how to package the eggs well, to ensure they arrive safely. I ship them using the USPS medium flat rate box (I usually ship between 10-18eggs in a box) and I also include delivery confirmation. I have been shipping them with a fragile sticker, but no sticker that says live eggs. If I put the sticker that says live eggs or live embryos, do I get charged more? Does it help to have that sticker on the box? Is there anything else I should do?
