Day 30- No Pip; Duck eggs

[BlessedChaosHomestead]

Ok 4 duck eggs. On day 30 for one. (They were each laid the day after the other. Earliest is the one I think is dead; 5/10 lay date.)
Think one has died. (egg issue, not the incubator)
Yesterday one was scratching in the egg like it was trying to pip. But still nothing. Last night, another one of the eggs jerked.
3 have life in them, but I'm starting to be concerned.

We have a Nurture Right 360. These weren't added until we had 10 days left due to momma hen being a bad mom. Never owned one before. Just going on what the instructions are. Humidity per readout is currently 79%. A bit high to what it say it should be for chickens. Temp is 99.5.

Is there anything I should do?
Too early to worry? Or act now on something??

Thanks!

Did you open the incubator any time around 3 days before lock down? If so you could have seeled the eggs in their shell

That's a wives tale, the lid can be taken off at any point in lockdown as long as it's not left off for awhile.

How would that seal them? And I am not sure. It has been opened though, yesterday, because the tray had failed to be removed.

If there isn't enough humidity, the membrane can get tough but unless you took off the lid and made sandwiches, they'll be fine

I don't think it is a wives tale, it has happened to me.

Gotcha. Yeah trying to keep it shut but have candled to check if still alive. So far egg 1 has a little breaking spot!!

If it doesn't hatch in the next 24 hours then you will have to assist it for it to hatch

Day 1 isn't when they were laid it is when the were incubated, so day one would have been when hen started sitting full time. If she never sat full time, day 1 could be the day after you put them in the incubator. Duck eggs can take up to 72 hrs after that first crack in the shell to hatch. Give them time! Do not assist unless it is 100% necessary. A duck that doesn't have the strength to hatch most likely won't survive anyway. I wouldn't worry too much about the humidity at this point. It CAN cause issues but doesn't always. Just make sure to keep an eye on them. Good luck with your babies let us know how it ends up.
