Not necessarily so....I've had 0% hatch rate when everything was at optimum levels for development and hatching...sometimes the shipping is just too great of an ordeal to overcome!Sounds like they may as well have played football with those shipped eggs.
Granted, shipped eggs are a big gamble any of us who order them take, but still, it's unheard of to get a 0% hatch rate when all conditions are nearly perfect.
You're going to be able to prove it to them to just not bother getting those eggs again, wherever they came from. I'd suggest they also give lessons to those in charge of receipt and redistribution or let an experienced chicken tender such as yourself be in charge of it. That may have helped a little bit.
