Are these duck eggs dead ?

[Jackrat]

I have a large incubator and I candles today . I have call duck eggs due to hatch next week but there were a few that look odd . I’m afraid to throw them away as I’m not sure if they are dead or not . There seems to be a black line around the air sac . I’ve moved them into another incubator for now

That is too far away to see

i would not trash them i would keep them in the incubator until 3 days after hatch date
