Incubating Duck Eggs!!! HELP!!! 1 is Day 21, others are on Day 8!

[houseandhomestead]

I was given fertile duck eggs so I decided to incubate them after many failed attempts with our own ducks. I had one fertile egg already in the incubator when I added the new ones. So the first egg is day 21!!!! 21 others are on day 8!!! What do I do!? I’m using the Nurture Right 360 and buying more stuff isn’t an option.

when they hatchs on the 28th day your others will have 13 days to go

Lockdowns at 25 days so thats 4 days of lockdown so the newest egg for its 11th 12th 13th and 14ths days wouldnt being turned and would need to withstand 20% extra humidy

might stick to the egg it might not devolope the air cell right its hard to say. I have zero experience though

I don't think there's a big concern. I had high humidity for most of the incubation period (due to the weather). In the last week b4 lock down the weather became a bit drier and I added some desiccant in to help. Those eggs hatched fine.

During lock down I also opened the incubator a lot to make safety holes and take the hatched chicks out. Some moisture was lost but only like 15% of the eggs were shrink-wrapped and I simply helped them out just fine.

So what I'd do is up the humidity during hatching, and then turn the other eggs by hand 2-3 times a day. (the most crucial period for egg turning is about the 1st 8-10 days so you should be fine.)

What I'd be more concerned about is how you'd brood them, especially the first egg, which would essentially become a single duckling. Then you'll need a separate brooder for the younger ones.

When that one egg is ready to stop being turned on Day 25, you would want to shut the autoturner off and just hand turn the others. I would keep candling the egg and not increase the humidity for lockdown until you see it has internally pipped, just to reduce the amount of time the eggs that are not ready to hatch are spending with the higher humidity. Once you see an internal pip, bump the humidity up to 65%.

Humidity is more important as an average over the entire incubation period than on a daily basis, so running the humidity a bit lower than normal for a couple days after the egg has hatched will even that right back out for you

I'd recommend you take @Pyxis highly experienced recommendation for you. Wait until an internal pipe for the humidity increase. Then you can run it a little low once your first duckling is out to balance out the other guys they aren't ready for lock down yet.
@PaulX Had another great point. You will need to brood the ducklings. The first one will be bigger and pick on the rest of the smaller ones.
Where do you plan to brood?
