infertile eggs

[peter g]

I'm new to the forum but need some advice.
I bought 35 Jumbo Brown Coturnix Quail in September. The guy I bought them from said they were hatched May of 2013. I have them in individual pens with one cock and two hens.
I have a cabinet incubator I used to hatch out chickens with quite successfully set to 99.5 to 101.5. It has a automatic turner, the last 3 days I put them in the bottom/don't turn them and increase the humidity to 65-70%.
I feed Southern States 21% game bird Super Breeder.
The first 25 eggs only hatched 5 eggs.
The next 40 hatched 1 egg.
The next 55 hatched 0
The next 93 hatch this Tuesday and I would bet 0 hatch....
The cocks are matting, I've seen them.
What in the world could be happening that I've set over 120 eggs and hatched 6 quail?

Oh, forgot to mention, only 1 egg out of all the eggs that were incubated showed any sign of fertility.

Check your temp and make sure it is correct...using a different Therm.

 bator temp could be the problem

but you mentioned eggs not being fertile

is it very hot where you live ? if so that could be why your males sperm count is down  when it cools off a little should pop back up.
if its too cold same thing

also how old are your birds ?
