Panicked!! Wrong duck air sac size!

[Camtheduckguy]

Tomorrow is the lockdown day.The air sac in the eggs are too small.What do I do? I can’t see anything in the eggs besides the air sac. Tomorrow do I poke a hole in the air sac? Help please!?!?!

What is your temp & humidity during incubation?
Could you candle & take a picture of what you're seeing?

You may want to update your profile with your location, helps knowing the time zone you're in and the weather conditions for those responding.

Thank you in advance for your help ...

Have you candled throughout the whole incubation?
Are you sure the egg is alive?

No, do not poke a hole just yet.
Can you take a few pictures in a dark room?

 

[WVduckchick]

Tell us about your whole process so far. What kind of incubator, has temp/humidity been stable throughout? What settings did you use?

Do NOT poke any holes yet. If it’s just lockdown time, I assume they still have at least 3 days to go, so no holes yet.
If they are really too small, you can delay lockdown for a day or two. There are a couple other things, but tell us more first.

Well it’s a janoel 12 incubator. The air sac is about half the size it should be. The embryos have been growing properly. Humidity wasn’t fine. Today is lockdown day. It’s winter.

Those are usually decent incubators, I believe. So I have to assume that you may have used too much water throughout, and they didn't lose enough moisture.
Your best bet is to wait another day, or even 2 more days, before increasing humidity even further. Watch for drawdown or even internal pip, if you are around enough to monitor them closely. If not, I'd at least wait for drawdown.

A couple pics of what I mean by drawdown.

What do I do when they internally piped?

What do I do when they internally piped?

Add water to increase the humidity inside the incubator.

 

[Camtheduckguy]

Would they run out of oxygen?

Did you trace the air cells, or can you take a picture candling so we can see the air cell size?
