So sorry to hear that. Are you letting the eggs rest for a period of time before putting them in the incubator so the air cells can reattach? Do you candle the air cells after they have rested to make sure they have reattached? If shipped eggs aren't rested long enough before putting them in the incubator, they may be left with rolling air cells which may impact malposition.
There's a really good article in the learning center about hatching shipped eggs. Perhaps you can read that, if you have not already done so, and see if there is anything you can try doing differently the next time.
It certainly does not help that the box is so beat up. Sometimes I wonder if people see "Fragile" stickers and decide to bang it around extra to see what happens. Will the seller or post office do anything to assist?
It is so frustrating to pay good money for hatching eggs, get excited about the new chicks you may have, and then have a disappointing hatch. Good luck!
