Duck hatching help

[Islandmom511]

So I’m left with 4 out 12 shipped eggs. Day 24. Went on early lockdown today because one was rocking and trying to internally pip last night. I upped the humidity and am staying steady around 79% and temp down to 99. My problem is, the other 3 eggs in there are no where near as developed as the one trying to pip. I wish I would have gotten a pic, but didn’t. The one that is trying to pip the egg is completely dark except for the air sac. The other 3 there is about 1/3 clear yellow with no veining and some super thick veins around the chick when I candle. I quickly candled the 3 tonight and saw movement in all of them, but the veins seem to be receding a bit each day. My question is- do I keep letting them cook since there are signs of life??

Do you think you could post pictures of the questionable ones? It won't hurt anything to take them out and get a photo, especially since you don't have any pips yet.

Here are 2 different shots of each of the 3 eggs. They have super wonky air sacs.

The last two photos look not so great, but all the rest look okay. Is your incubator forced air or still air?

Oh good! I’m not sure? ‍ It’s the little giant, but I don’t believe there is a fan.

Still air, then. I'm wondering if you had a hot spot where the one egg that's ahead was sitting, and that's why it's further ahead in development.

Possibly. I didn’t rotate the eggs around the bator, but I suppose I should have.

So should I let the iffy ones stay in the bator while I’m on lockdown with the 1? Should I continue to turn since they seem underdeveloped?
