Khaki duckling in shell day 29 with unobsorbed yolk

[Newhatchlings]

Hi everyone. I just hatched some khaki ducklings but one is having some major issues.

After i noticed a lot of bruising on june 28th i thought it had perished but then it pipped the wrong end. I left it like that for a couple days but after 48 hours i attempted an assist following the guidlines on that website everyone here puts a link to. But im still concerned cause now another day has gone by and no progress. The yolk still seems like its not obsorbing at all. It still has an unobsorbed yolk sac on day 29. It externally pipped at 10am on June 4th after I noticed a lot of bruising on June 28th

We are going on many hours/days since the external pip. There was no internal pip because it is backwards in the egg so I thought, ok more time. But at about 50 hours I exposed a small bit of the air sac area and seen the yolk. It's been 60 hours and still the yolk is the same. I don't think she's able to obsorb it and my question is. How do I assist further. I am afraid to slowly open her up because she is on the veiny side of the egg. I can't clearly see if she has her foot over her head but she's not shrink wrapped...however that exposed membrain around her hole I did open a little and now it's hardened. I put coconut oil on it and watch her closely but she just keeps trying to pip it looks like.

Anyway, any help is greatly appreciated. I see tiny little red veins at the yolk section that are red and know she needs her yolk or she is likely doomed. But how many hours before she perishes if I leave her like this? Anything I can do to help her? I can't see how she would have much longer to survive like this.

Any help is greatly appreciated

Here are some pics. I've opened the air cell slightly too and that's where I see the yolk. I've put another shell over it to keep it from drying out like the pipped hole. My humidity is still at 72 temp at 99. The rest of the eggs went fine and are now out of the incubator. This little guy is still breathing and chirping

Happy to say we have our final hatchling. That's 4 of 4. We will keep her in the incubator overnight to dry and get her some food tomorrow.
She did get all her yolk and was zipping when I got home at 11:30pm today.

I wasn't going to intervene any further until 2morrow or the next day but I was worried her foot was above her head but she was ok to zip, thank goodness. Knew I had to wait because she didn't have the yolk obsorbed and too many blood vessels around her because of her positioning.

But if this continued for another 24 or 48 hours what would I have done. Like if she was positioned in such a way she wasn't able to zip than what? What if she was tiring but hadn't obsorbed the yolk sac. I've read that sometimes they can't obsorb the yolk because of there positioning, is that true? If that was the case, would there be no way to reposition her so she could get out??

I still would like information incase it happens in the future. I found info on assisting malpositioned chicks and info on timeframes but what about chicks that are malpositioned with there foot over there head and pip on the wrong side and can't zip with unobsorbed yolk? Then what can you do?

Do you just wait until their yolk is 100 percent obsorbed? What if they aren't obsorbing the yolk for days? How many days is too many days?

Thanks everyone! We will keep a close eye on her and hope she makes it through the night. She seems pretty tired but I know she just obsorbed that yolk so she's good on food for the night.
