Eggs dying??

[Kanrayhen24]

Hello everyone. I am incubating some indian runner duck eggs and I think they have all died I could see clear distinct veins in all eggs when candling and then one by one next time I checked the veins look really light and there is no movement whatsoever. I am really not sure what's happened.

We’ll need more information about your set up. Temps, humidity, automatic turner? Are you only going off the built in incubator temp/humidity readings? Forced air or still air? Shipped eggs or from your own flock plus how old they were when you started. At about what day in development do they seem to be dying off at?
