bad batch of eggs

[tonij1271]

I tried hatching 20 pharoah quail eggs.  Not a single egg hatched.  Tried 20 again, still not a single egg hatched.  Tried one more time with different incubator and still not a single egg hatched.  But from same birds, I have had a very good hatch rate.  First time it was 16 out of 16, then second time it was 21 out of 27.  Can anyone tell me what is going on.  Right temp and humidity.      :roll:
Please someone help me.

How old are your quails, I brought a nice looking trio and was told they were young, after a few hatches wasn't getting any chicks, so i put my male that i got with a young female that was reliable stuck the eggs in the incubater and candled at 6 days, (I normally don't candle) all were infertile the male was a dud so I say he was pass his used by date

Infertile eggs is what it sounds like to me also. Have you tried candling any of them?  If not, you should. It's very easy to do.

i thought the eggs might be infertile, but I did not know every one would be.  I have tried candling with a flashlight, but i could not see anything because the eggs are so dark and speckled.  To answer first reply, my females are getting pretty old, and i have recently put some younger males in with them.  i really hope that helps.
