Duck egg hatching

[Hammertime]

Hi guys, I just wanted your opinion especially those who have incubated duck eggs. I incubated 9 eggs and 6 have hatched so far. This one egg has not externally pipped yet. While the rest have. I have the candled pictures here. Is this egg dead? Or do you think I should give it more time in the incubator. I drilled a small hole in the air sac because I was concerned but I didn’t know if it just needed more time or if it’s dead. I don’t see any movement but I also have two more eggs that just pipped not that long ago.

Just looking for your opinions. Here are 3 picture of the egg in reference. Thanks in advance guys!

Gosh, sorry nobody replied. How did it go? Hopefully, you've got some cute fuzzy ducklings!

Yes, hatched 7 out of 9. They are cute ones. The egg in question was not alive, but the others are healthy and happy. Here's a picture in reference for the ducklings. Here is my niece with one of the ducklings.

I decided to be crazy and start the incubating process all over with eggs from our own ducks instead of a hatchery. So far all 8 are growing.
