What kind of quail? If coturnix, then you incubate them at an average temp of 99.5 and 55-60% humidity. You lock them down at day 14 and increase humidity to 70-75%. They will hatch between 16 and 19 days. Some recommend hatching them in cartons so they stand vertically with the large end up.
If you are talking about another type of quail, I am pretty sure the temp and humidity levels are pretty much the same, but the lock down day is different. I am sure others will respond for other quail, but it would help short cut the process if you posted the breed.
