Duckling eggs all dying after zipping has begun

[Adolfus Nile]

I had one duckling hatch 2 days early and now 3 eggs that have begun hatching on time just to give up during zipping, peeping also stopping. They seem dead to me. What could be the problem? first time incubating.

Are the air holes open in the incubator?

The first two that appear to have not made it the air holes were not open, but the humidity was a little too high when the next egg was hatching so i opened the air holes.

Air holes need to be open for hatching. They need that extra oxygen avaliable when they pip

Sounds like the first two did not get enough oxygen. I'd keep the air holes open in future

Do you know they are for sure dead or just resting
They sleep while absorbing as this process is 24-48 long and exhausting
I have had many that don’t peep at all and done that do but go quiet for periods of time

As for humidity jumping while a baby hatches this is normal
I never worry as a wet baby causes it to spike and has never caused harm to my other eggs
I myself never cover those holes not even in incubation
I leave mine open 24/7 from day one to hatch
Sure hope everything is okay

I am waiting hopeful that they are not dead

They could just be resting
Try not to stress out to much ( easier said then done )

I agree there is a good chance they are just resting, BUT you have to open all air vents when it's hatch time regardless of humidity. Hatching is very strenuous which means ducklings will get quiet and take breaks for sometimes hours at a time. It also means they need as much oxygen as possible. Ducklings hatching in an incubator with the vents closed would be like someone putting you in a sealed box and then telling you to break free.
