How Early Or Late Can Coturnix Quail Hatch?

1 Surefire Way To Solve This Is Get A Fine Pt Sharpie Marker And Write The Set Date On Top Of The Egg As You Set Them

This is our last hatch till spring, and we decided to hatch some of my sons' quail eggs. We put 7 in the bator on the 4th (in the AM, around 10ish), but one went in the day before,making a total of 8. We had the early one hatch on the 19th (it went in the bator on the 3rd), then had 2 hatch yesterday, then another just a few minutes ago. Still have 4 in there, no pips or rockinh or peeping from them.

I did have two temp spikes in the last 10 days- both went to 104 (

) but only for maybe 2 hours before I noticed and corrected. I dont think it was long enough to speed development of the chicks, and it would be weird for only a few to be further along than others, right?

If it helps, I am using an LG with fan, used an egg turner till lock down. Humidity was around 30-35 till lockdown, then it goes up to about 44-50, maybe a tad higher during hatch.

Sorry I was so long in getting to my actual question! I was wondering, how early can they hatch, and how long should I leave the stragglers in the bator waiting for them to hatch? I dont want to disrupt the temps or humidity to do a water test since they are (maybe) so close to hatch.

Whats the longest incubation time anyone has had when hatching coturnix quail? Or do I have my dates wrong?

I had a Cortunix Quail hatch on day 22. Let this be known for the record.
