What is this in the air sac of a duck egg?

[Miss Cheep]

Hi! I have a duck egg on day 27, almost ready to hatch. I was candling it today and saw some weird stuff in the air sac. The mother of this egg has never had a duckling before. Is it possible that the duckling internally pipped and stuff from the egg got in? Thanks!

That looks like a dead egg unfortunately.

I agree with @MGG this egg appears to not be at hatching time stage at all.

Are you sure you saw a duck inside it?

Yes, this just appeared today. Yesterday it looked like a normal duck egg.
