Early hatching?

[Libby]

I may be posting this question too early, and just need to be patient, but THIS IS MY FIRST QUAIL HATCH!  Hubby bought 120 Georgia giant eggs to fill the incubator.  We've had consistency with our thermometer in the past, so I don't think the temp was too high.  Today is day 20 (I remember incubation tome for those being 23 days?) and this afternoon I took them out of the turner and candled the first 20 of them.  All were developed except three, so I discarded those three and put the rest in the 'bator to expedite the process... Now, six hours later, I check on them and one of them almost has the cap off his shell, and I see another egg wiggling!  What is the DEAL?

Only two reasons to hatch early.

Counted wrong.

Temp too high.

Hope you bumped the humidity up for the hatch...
