What is this organ looking thing in egg?

[jtink1203]

I have hatched a couple eggs but they usually do it themselves and I toss the eggs after. 2 of my eggs suffered from low humidity and they got sticky and glue like after the pip. I successfully helped one out. This one has been constantly struggling and crying trying to get out. I removed a little of the shell and carefully peeled back some of the membrane. I got a little scared when I came across this organ looking tissue. Is this the yolk sak or is she premie?

Looks like a yolk sac to me. @MGG

You need to leave it alone until the yolk is absorbed.

I’ve never thought about it before. I just know it’s nothing to worry about.

That is the yolk sac. It looks like you helped really early and much to fast. It can take up to 72 hours for a duckling to hatch on its own. With that much yolk still attached hopefully it will finish absorbing on its own. Make sure she doesn't step on it or break it as it can result in bleeding to death, infection, or pulling out her innards.

Ok thanks. How do you know when the yolk sac has been fully absorbed? We are leaving the bottom of the egg attached for now and it is back in the incubator. Letting it dry out and absorb yolk sac as of now.

We are completely new at this. It had pipped and we noticed the membrane of the egg that was showing was dry, thick and yellow. Upon further research concluded it may be shrink wrapped. We let it be for another 4 hours but thought it could be stuck. When removing more egg shell the membrane was partially stuck on and shrunken from egg shell. We are leaving the rest of the egg on with yolk sac attached. I hope it makes it.

As long the yolk doesn't get damaged, she should be okay. You just have to be really careful when assisting as one wrong move can seriously hurt or kill them.

You won't be able to see it anymore. They will also still be sort of "yawning" if they are still absorbing it.

Thank you I appreciate the info!

Welcome to BYC!
That's the yolk sac, yes. Put it in a paper towel lined bowl, with the egg, in the incubator. Leave it there until it's done absorbing. That way it can't drag the sac around and break it open. If it break open, that's usually fatal. With eggs, just for the future, don't assist until it's been over 24 hours with no progress. At lockdown your humidity should be at 75% to avoid shrinkwrapping, and if you assist any, stop immediately if you see blood and don't touch it for at least another two hours.
