Shipping probably did it although I would not think every egg would be bad. I incubate shipped eggs all the time--I usually get between 4-6 chicks out of a dozen + 1 or 2 extras. I don't expect a high hatch rate from shipped eggs but I don't expect 0% either. What breed were these eggs? Do...
What you are seeing is a blood ring--early death, I'm sorry. The egg is not viable. A fertilized egg at that stage also does not have the yolk flopping around in the direction you move the egg.
