Big airsacs

[you-da-chick]

Its day 7 on my 8 shipped silkie eggs, and 5 of them are definitely developing. Problem is the airsacs are large and abnormal. There is the usual air cell on the big end, but then there's an additional air sac that takes up almost half of the egg. I keep humidity around 46, but I raised it up and now it's at 60. Is this too high, or is it appropriate in this scenario? Also any other tips to help them hatch?

There's an article by Sally Sunshine about "shipped" eggs that's very informative.

When you got your eggs, did you allow them to settle (pointy side down) before putting in the incubator? Sounds like you're dealing with "saddle" air cells.
Where are you located? The humidity sounds ok (35% - 45%), read that most raise the humidity at lock down (70% - 75%).
What is your temperature?

Hang in there, the more experienced will be chirping in ...

How are you incubating the eggs? On their sides? Or pointy side down?

I would incubate pointy side down, especially if the eggs were a bit scrambled with shipping. That helps gravity to get the aircell all in the top fat end.

Also, humidity is best close to 30% for the first part of incubation. 25 to 45 max for humidity.

When you say that the aircell is so huge... are you looking at the aircell? Or the -not yet filled in by the developing baby chick- part of the egg white????

Yes, when I got them, I made sure to rest them for 24 hrs.
They all had the pointy end down. My temp stays pretty consistently at 99.5. And I live in Sacramento CA, so not totally dry, but not humid, around 40% on average.

The type of incubator I have is a Janoel 12 with an autoturner, so I can't put the eggs up vertically:/.
Also about the aircell, I'm not exactly sure if it's the air cell or just empty space, but I'm leaning towards air sac, as there are no blood vessels in that area.

Update
Now I'm confused . So when I candle the eggs, I can see the light spot which is the air cell, and they all seem to be in the normal position, then there is a large light patch that seems to be separate from the air cell. It's a little darker than the air cell, but lighter than the mass where the chicks are. So is it just an empty space the chick hasn't filled out yet? Or is this still an air cell? Any pictures that I can look at for reference?

Sounds to me like the area that the chick hasn't yet filled in.

There are articles here on BYC about hatching... most have nice photos.

Did you get your humidity back down? 60% this early is bad.

I hope so, I'm looking at a bunch of pictures, but none seem to illustrate what I have.
It's was at 60% pretty briefly, and now it's around 50. Should I keep it at 50% or a little higher?

I would have it lower...

35 is nice.
