My Muscovy duck has been sitting on her eggs for 37 days now and the eggs still haven’t hatched. No piping, nothing. I candled six eggs and I can see movement inside the eggs, everything devolved how it’s supposed to (or at least in comparison to pics on the internet). Is there something wrong? Am I supposed to intervene at this point? And if so what am I supposed to do?
 
So an update on the eggs. It’s been a week since I projected the eggs hatching, they still haven’t hatched but mamma is faithfully sitting. I went out and candled all of the eggs. All 31 to be exact. 15 were definite duds. Three I was unsure. 13 had movement. So I put the eggs back that had movement and threw away the duds, left the three maybes with her. Anything I should be doing at this point? Or just let nature do it’s thing?
 
Update on the eggs. They hatched today. 12 of the 16 that were left over. Almost all of them look happy and healthy. However one of them seems deformed. The chest is abnormally larger then the other ducklings, it’s almost always on its back and the neck is constantly crooked.

Thank you all for your advice. It helped to ease the stress and tension.

according to my research the incubation period is 35 days average, certain factors can throw this off and the babies still could hatch especially if there is movement. When we raised quail i still had chicks hatching four to five days after that period. I set my incubation limit to a week/ week and a half extra time just in case. after that i would call it quits with the eggs. It is bad to intervene in cases where chicks havent hatched yet due to possible underdevelopment. Give them a few more days, the discard after a week or so. I hope they hatch for you !
 
No, do not interfere.
They aren't even internally pipped yet.. you cant just go cracking the eggs open, they would likely bleed to death/not absorbed yolk, etc
 
Just wait it out. If you see movement then hopefully they will hatch. Maybe you were off on you counting?

Always possible. I’m still new to this. I read that you start counting when the female becomes broody and sits on her eggs and only gets off them once or twice a day. Are there other signs I could look out for to get a more accurate time?
 
You shouldn't be that far off, but if your seeing movement I'd say something caused a delay but as long as they are still alive that is what counts. Next time you candle listen to the eggs too. Might just hear some peeping. Usually once ready to hatch they take up so much of the egg all you can see is the air cell and black. Can you tell where the air cell is was it dipped down at all?
 
Is it possible that you have a staggered clutch? Is the nest accessible to your other ducks? Perhaps she has collected more eggs since originally setting. Maybe the eggs currently developing are newer eggs. Is there any way you could get candling pics and post them? That might help us to determine what day they are on.
