Are my eggs dead?

[Khaki mama]

Were on day 27 of incubation and a couple of my duck egg have very light gray splotches on them. Were in lockdown so I didn't open the incubator. Should I candle them? Are they dead?

Never mind this one blotch is almost blue and I read an article that their trying to get in position and nicked the side with a toenail or something. Anyway I think this problem is solved. Thank you anyway for reading.

How did your hatch go? Did the ones you were concerned about hatch ok?

No, we just got the one but we have a new batch going. We cracked open the eggs that didn't hatch. One was a quitter and didn't develop all the way and one was positing the wrong way. The other two looked perfect still don't know what was wrong with them. Hopefully this batch goes better.
