Please Help. My Coturnix not hatching at all?

[savannahRoos22]

I am so sad. Why do chicks just die in their shell? And why are they all like this in my recent batch?
7 Coturnix Quail:
99.5 Temperature.
20% then 60% humidity
Their air cells are good, and some could be in a bad position, but why all of them? There is not a single pip.
I know the humidity is pretty low, but winter Utah has really dry air. and I have two thermometers.

Have you had success with 30 40 humidity at the beginning? And if they've grown still, was the humidity not the case or does it only effect them towards the end? Some may be almost fully developed because the one I had opened had yolk still. But they were healthy for a really long time.

I turned them 3-4 times a day. 6:00Am , 3:00pm, 6:00pm, 10:30pm
They've been in the incubator 20 days. and on their 14th day, I started the higher humidity. 15th, I layed them on a soft feet friendly surface and stopped turning.

And I really dont want to make a mistake like whatever ive done again. I'm devistated. Please help!

Did their membranes shrink!? Did they Drown!? I cant figure out what to do?

I think it might be the humidity. Its way too low. It should be at a constant 40-50%. Is it a still air or a fan incubator? If the temp's been fluctuating -especially if it's gone up- it might have affected your hatch. You know, they might just be late. I wouldn't stress until after five days. Just, don't open the incubator -its deadly.
