Weird duck hatching, yolk sack still attached

[jestep]

So we just hatched 14 ducklings, most went just fine, the last 2 have been really bizarre. The second to last one was the first to hard pipp and then decided to do nothing for more than 50 hours. She did make it though, but we about screwed it up completely helping her, but she was finally able to get free.

The one we're currently hoping makes it hard pipped and pecked a roughly half inch hole in the shell, very similar to the other one. We left her alone, and she hadn't progressed in about 55 hours, so we widened the hole a bit just around the air sac, the whole time it would stick it's beak out and chirp a lot, but never zipped. We looked in this morning and literally, the entire egg was full of liquid yolk. We heard her sneezing because she was drowning in yolk. So, my guess is it was a double yolk shell and popped the second one thrashing around with it not being used and about drown in it, does this sound normal or logical?

After that it managed to squeeze out the hole, but still somehow hadn't absorbed it's own yolk sac, so we are trying the cup with wet paper towel method hoping it survives. Have never seen anything quite like this, although I'm no expert on hatching ducks, just have done it enough in the last 7 or so year to know this isn't normal. Feel really bad for the thing as she's been covered in sticky yolk despite our efforts to clean her.

Any other suggestions, our incubator is very good at both temp and humidity control, we're really just hoping there's a way she can pull through this one.

Sometimes a chick or duckling instead of pipping and zipping, they just make a hole. The ones that just make a hole always need some assisting because they don't zip from the hole.
About the yolk sac breaking: it's not good, there is nothing you can do but wait. Be prepared that it will probably die.
Overall it sounds like you had a good hatch, there can always be things that go wrong but it's sounds like a pretty successful hatch to me.

That's the weird thing, it's yolk sac is totally attached and undamaged still. It was like another yolk was in there.

How large was the egg?

Sometimes it could be a double yolker.

How large was the egg?

Fairly large, our ducks lay roughly a jumbo plus chicken egg.

That's what I'm hoping and the other yolk took up so much space it was able to just squirt out of the hole it made. No bleeding at any point, her sac is totally intact. She's still feisty and in good spirits as well, probably not much else we can do but hope she pulls through.

Pic?....I am sure it was a double yolk

She's in a cup now and I don't want to move her much, we didn't unfortunately take any pics at the time we were moving her, I can take a picture of the yolk we poured out though but was just normal yellow as if out of a somewhat fresh egg. We didn't see it candling though, but couldn't come up with any other explanation for it.
