Hatching Troubles - No progress after external pip

Hi everyone,

Though I don't post often, this forum has been a HUGE help to me over my past two years of duck keeping. This year we are incubating eggs for the third time. Today is day 28, and I'm getting concerned. Our first hatch went BEAUTIFULLY. They hatched a little early, but everything was just picture perfect. Our second hatch was a disaster - We had a bunch of fully formed (or nearly) ducklings die. I think our humidity was generally too high, and then spiked when we had some unusually humid weather.

This hatch:
We kept our humidity much lower (around 40%), and weighed our eggs to try to achieve around 14% weight loss - which we did quite well! Everyone was moving and grooving as of day 25. I raised the humidity levels at lock down, but I'm afraid I didn't raise them enough. I also think I brought the temp a little too low (97ish) for a bit when I adjusted it down for lockdown.

They are in cartons that are tipped at around a 45-degree angle (so they aren't quite on their sides, but they aren't totally upright either).

The first egg to pip externally was about 36 hours ago (day 26). Others have pipped since then (within the past 24 hours), but no one has actually broken through the shell with their bills - they've just made cracks. Some appear to have begun to try to begin unzipping (there is a large "pipped" area), but again, none seem to have broken all the way through, and many have made little to no progress since the initial pip. I removed a chunk of loose shell from the egg who pipped so long ago, just to see if perhaps it was shrink wrapped. Though the shell was cracked, the outer membrane was completely intact. I ripped through it (carefully!) to check on the duckling (who was very much alive), and the inner membrane didn't seem particularly gooey or dry.

Is this okay? Is there a chance that outer membrane is extra thick/dry so the ducklings can't really break through? What could I do about that? Maybe they are shrink wrapped on some level? Am I freaking out way too early?

The idea of otherwise-healthy ducklings trapped in these eggs is making me a nervous wreck! My biggest concern is that the way they are pipping just feels very different from our first, successful, hatch. Any input would be greatly appreciated. I've seen such a lovely supportive group here, and I could definitely use that today! Thank you in advance!
 
Do you think I should lay them flat? Or would changing their position at this point be a bad idea?
 
The slightly lower temp would lead to the eggs hatching slower, just give them some time, and I hatch my silkie and quail eggs flat too at lock-down and have had great hatches. If the inner membrane isn't wrapped around the chick, it should still be able to hatch due to being able to move even if it is a little drier than usual.

I had one egg that was a late pipper after all the other eggs had hatched and it even pipped in the middle of the egg instead of the airsac, it still tried to zip but it seemed the veins were stopping it, as it made a eggshelless hole but the membrane was intact around it barring the initial pip hole that had gotten a little larger. I shown a candler through the airsac and the bump that was the beak moved up, so I put it back and when I checked later, it was sending eggshell across the incubator with the force of it's zipping! It didn't take long at all to go from air-sac pipped to zipped and out of the egg peeping as loud as could be and falling into another egg. :p

So if you feel any might be pipping below the air sac too, show them the way via a light.
 
Thanks for the input so far guys :)

I have a couple little updates: The egg that began pipping over 36 hours ago continued to be lively, without any progress. After a while, she was able to turn a bit, and we could see a foot! We figured out she was trapped under her foot and wing. She began trying really hard to push out of the egg, and was able to do so after I removed a little more shell so she could maneuver. Unfortunately, though I feel confident she needed help, I might have helped a little too soon as there was still some veining/blood in the shell. She seems stable, though!

During this time, another duckling unzipped and hatched beautifully. It still seems the other eggs aren't making much progress, but I wonder if @MageofMist was correct, and the lower temp I had a few days ago just delayed things a bit.
 
How did the hatch go?.....

Thanks for asking :) It's still progressing. We have not had any more malpositioned babies, and definitely no shrink-wrapping issues - yay! Things have just progressed rather slowly. All 8 babies that have hatched look great! We're still waiting on 7. I'm hoping they don't take too much longer, but I think I was freaking out over nothing ;)

I started another thread with photos of our Welsh Harlequin babies for some help sexing them based on their bill color. We also have some super cute mixes, including a couple "surprise" eggs a friend gave us, that turned out to be a mallard mix and a silver runner mix. So cute.
