Problems Hatching Call Ducks

[chickens really]

Yes I have been keeping 65 percent humidity throughout the whole incubation. I will drop the humidity and hope that it helps

I believe that was the issue. I incubate at 40% and watch air cells. I lockdown at 60%

Is 50 percent good. I've heard ducks need higher humidity than chickens? Also a lot of websites all day different things so it can be a bit difficult without asking someone who has actually had the experience.

No. I hatch Ducks and chickens at the same setting always.

Ok then I will lower humidity to 40 and increase it to 60 at lockdown. Maybe cancel before lock down and see were the air cell is at.

50% is still way too high for my eggs in my incubator. Hopefully, @Pyxis and @WVduckchick will chime in with their suggestions.

Here is an air cell picture that might help you. These air cells are borderline too small for my liking, but they should be a good guide. AS in if your air cells are smaller than this then your eggs are not losing enough moisture.

Another thing is high altitude pressures slow the gas transfer through the egg shell so altitude can effect the aircell, if your 5000feet over sealevel ide do some research on that

i heard that in the last week of incubation if your aircell is way too small you can scrub the bloom off the shell at a spot of the egg shell right on the aircell and it gives a spot for gasses to pass through easier and can grow the aircell. ive never tried it or seen anyone do it so dont take my word for it. Have any of you heard this?

You can drop to 35% if the air cells really need to get bigger. It generally takes anywhere from 24 to 48 hours to get the moisture out.

Nope. I have never heard that one before.

Okay, i might have dreamed it up

I'm sure you read it somewhere. Lots of theories on hatching and I just keep it simple.

You didn't dream it up. Hatching at higher altitude does require different techniques. And when eggs aren't losing enough moisture, some people do remove bloom, heck, some actually sand the shell. People will also cover eggs with tape if they are losing too much moisture.
