Please help

Hmm, it's hard to say whether the humidity is correct with not knowing how far along it is and angle you have it on the video, and I wouldn't want to make a stab at it - there are far more experienced people here to give you a more informed opinion! But at least you've not had it so dangerously low the inner membrane has started peeling away from the inside of the shell and that's what's causing the dark spots! Although who's to say what conditions the eggs were kept in before you got them....
I will try to find a good duck egg chart for you to look at, it will probably be easier for you to compare with the egg than anyone try to gauge from pics

I think this will help
To me it looks around the 24 day mark maybe? That would make sense too as I think I read these types of eggs are about 14-18 days in, so add on your 5 days of incubation and that would be about right. So presuming they aren't muscovy eggs which take longer, they could hatch fairly soon. Hopefully someone can advise on humidity/air cell size if they agree on development

Thank you so much for your help here's a video showing moments

 

[Emmaxx]

Oh definitely saw movement then!
Not sure if it's the angle or the background light but that almost looked liked movement in the air cell.... Or am I imagining that?

 

[Jay2695]

Lol that's the movement I have been seeing for the last few days I hope he or she is okay

 

[Emmaxx]

Well if it's like a shadow moving around in the air cell, and it's not just residual obsessing over my own egg, then I would say its getting ready to start hatching!

Any updates @Jay2695?

Hey I'm sorry guys for some reason I wasn't getting notifications please watch the video any ideas I have began to believe that the other ones are all dead except this one

That is an internal pip. . that means the duck has pipped the inner membrane and is starting to breathe air from the air cell. That's a good thing. It can take a long time still from this stage to hatch. Just put it back in the incubator and wait wait wait

If all goes well, Next it will externally pip (it will make a hole in the shell) and it can still be a while before it will begin to unzip.
Do you know what kind of duck egg you have?
