If the eggs were going to develop, you would have seen veins and a tiny heartbeat or embryo after 50 hours.
True if shipping had no impact on the egg starting to develop. However, I've opened many eggs at 40-48 hours for research dissection purposes, and the blood island isn't blantely obvious at that time point. In winter, we would have to set twice the number of eggs to get the Stage 10-12 embryos we were looking for, and after the eggs were shipped just a few hours from the source, it would take about 6 hours longer for us to get what we wanted, just with winter vs summer. It takes about 30 minutes for a new somite to form, and I was looking for a window of +- 1 somite. I've used thousdans of embryos, and for especially a first timer, 50 hours is cutting it very short to draw a line of fertile vs not. If that 50 hours was really 45, and they were 5 hours behind with a slow heating incubator or impact of shipping, that is a difference of a chick with two to a chick with 16 of them and a turned head. An egg at 60 hours will have a very obviously bloody chick. The first week is where the majority of development occurs, after that, it is just growing parts out from those initial stages.
