I have received eggs shipped twice, and both had hatching eggs written on the outside of the box, top and all 4 sides. They were also both shipped priority mail. One person wrapped each individual egg with bubble wrap (20 button eggs...UGH) plus put bubble wrap in the box, as well as wadded newspaper. The others were shipped in quail egg cartons, and packed in a box full of shredded paper. Out of that batch, I had one broke, but it looked like it was probably cracked before it was shipped. The others came in perfect shape. The buttons had do not x-ray written on the side, but as far as whether or not they did, idk, cause they are quail, and almost impossible to see into. We'll see in a few weeks how well the P.O. did on the shipping.
