The eggs where basically shipped they travelled 700 km with someone who brought them for me from another town.
The jostling around during transport may have played more of a role than temperature, as blood rings indicate embryo death early in development (usually the first 3 to 5 days of development). Rough handling can damage the air cell, weaken the egg membranes, and damage the embryo, all of which can contribute to early embryo death (blood rings). This is the stage at which I've lost shipped eggs.
The temperature is also an issue for successful incubation, as it should be 37.5 degrees C (99.5 degrees F).
I hope your next attempt goes better. Don't give up!
