Saddle shaped air cells

[Chickfever]

what causes them? I'm on day 21 with no signs of pipping or movement.

To make a long story short, I won some eggs from a seller, received 30, 4 were broken. On day 14, candled and only had 12 that had grown and were fertile. They had saddle air cells then.

Temps have been 99.5 - 100, humidity 36-46% for first 18 days, then 76% for the last 3. No known spikes in temp or humidity, not my first hatch, but first time with this breed (not sure that would make a difference). Any ideas?

Oh, and I added some silkie eggs 3 days later that are normal looking. No funny looking air cells and apparently thinking of joining the circus after hatching the way they were flopping around in those eggs. Today makes day 18 for them.

Thanks!

There was a post today on the subject scroll down and U will find it.

I think I read it, but it said everything should be fine (is that the one?). I just can't figure out why some would have these funny shaped air cells and others wouldn't when they are only 3 days apart. Shipping maybe?

ETA: I see you are from East TN, what part?

Just happens. I've set eggs all at the same time and some develop those lop sided air cells, and others are more even around, but they seem to hatch just fine either way.

Thanks! I'm keeping my fingers crossed on these.

I think it is from shipping. The membrane pulls away from the shell around the top, and makes for funny patterns when candling. I just opened some of my non developing crazy shaped air cell eggs, and the membranes weren't attached around the top.

That's what I was afraid of......with some, when I candled and rotated the egg a little, I could tell the membrane wasn't attached. Anyone have any hatch with a membrane that wasn't attached?

Thanks again everyone!

Of my 6 duck eggs, the one with the funny-shaped aircell was the only one to hatch, so don't give up on them yet!
