Duck eggs with no air cell

[Anime2lover]

I'm looking for advice if anyone can help me, I have 6 pekin duck eggs in a brinsea mini advance which are 14 days old, they are all moving well and have lots of veins but only 2 out of the 6 have air cells, is this a problem at this stage ? My humidity is around 52% should I reduce it ? I'm nervous because this is my second batch of eggs and only 2 from the previous batch developed but then died at around this stage, I had a cheap incubator tho so assumed that was the reason .... should I be doing anything ? The eggs are on an automatic turner but they don't all turn how they should .... any advice would be appreciated

It can be hard to see the air cells in a duck egg sometimes. They have thick shells. However, they should be fine. Your humidity is where it should be.

@MGG what do you think?

The second picture im assuming is the air sac ? This is in two of them

Saddled air sac, where an egg has more then one air bubble inside it. I've had up to three before. They can hatch healthy but there's a high chance they will try to hatch out of the wrong area. There isn't anything you can do about a saddled air sac.

Welcome to BYC! I see you're newer here.
What kind of incubator is it, and have you checked the temp with a calibrated thermometer?

I have a picture of one of my eggs but 4 out of the 6 look like this, does it look normal because there are no air sacs ?

The top one looks like it may be a quitter, but it's kind of hard to tell in the pic.
Everything about the second one looks good.

I don't see any saddled air cells in any of the eggs pictured.

I messed up the quotes somehow, sorry if anything ended up confusing.

Thanks for all the advice, I have a brinsea mini advance .... I decided to start hand turning them 5x daily rather than the automatic Turner and I've dropped the humidity just to see if that helps produce some air sacs, do you think this will help ?

No problem! What is the humidity down to now? It should help some.

I dropped it down to about 48% I was worried too but everything I was reading suggests to do that to increase to air sac, fingers crossed it works as still no air sacs ! So nervous.. don't want them to all die as they are growing so well

Ok. You could probably drop it a bit lower even, like around 40%. I've incubated ducks around 30% and had a good hatch rate. The air cell being too small won't kill them. I've had some chicks not even use the air cell, and pip away from it and they always hatch fine.
They'll be ok. It just makes hatching easier on them if they have a large air cell. And it will always get at least twice as big at lockdown.

Duck eggs are supposed to keep the humidity at 55%. Personally wouldn’t mess with that

I've still kept it between 45-55% just keeping it on the lower scale for a few days as I started with it at the higher end, I think the problem is that they are in my kitchen where the humidity fluctuates when I cook, the eggs are starting to wiggle so keeping fingers crossed
