Extra large "air sac"?

Why not? I hatch on a wet paper towel every time.

With it touching the egg? Do you dry incubate in a dry climate?

I dry incubate in a humid climate. I have an Incubation cheater in my signature I follow, keeping 4-6 incubators in action constantly.

I think most folks feel eggs can 'take on' water, when my experience is that they don't take in water but can fail to evaporate enough over the course of the first 18 days, hence drownings.

I hatch on wet paper towels after 18 days as dry as it gets. This works really well for me.

Of course, every person has to find what works for them, but since we're talking about a really large air cell, I'd boost the humidity way up for the hatch.

Ok, out of worry (and while putting wet paper towels in there) I checked the few eggs I was worried about. I see a definite head/beak which I didn't see last week. It's very close to the air cell, which again, it was not last week. But I don't see any movement still nor do I hear anything. The others were just all dark, I couldn't see a thing.

Again, the real hatch date is unknown. My rough estimation is between yesterday and this weekend. It would be so much easier if I knew!

The egg can take on water, but it's very slow unless the towel is connected to a water source, then it can occur at a more rapid rate. After about 14 days, the egg gets microscopic pores in it to allow easy opening by the chick. So the pores become large enough for water molecules to pass through... Ie- a semi-permeable membrane... If it was dry throughout, then it wouldn't hurt for a damp rag to touch but a rag acting as a wick would be a little too much exposure IMO

Oh boy, now I'm even more confused! Paper towels or no paper towels? Small water dish or not?

lol

I would put them on a damp paper towel and put water in the bottom of the bator. Not touching the towels that are under the eggs.

That way, they can only absorb the amount of water in the paper towel, plus the ambient humidity of the incubato

ETA: ChooksChick, I in no way meant to belittle you or your knowledge... I'm sorry if it came across that way, as I enjoy this forum and all the people here...

No offense taken at all! I absolutely advocate for sharing and learning! I agree- if the eggs were subject to humidity, it would be a poor idea to allow them contact with something damp.

I'm following you're cheat sheet and I live in a humid clmate and I just had one hatch yesterday and am hearing peeping today from the others
