The incubator will stop the turning on Day 14 and at that point you can remove the quail ring and sit the eggs on the cloth. Then they have a day or two to twitch themselves into the right position for hatching. They should pip at any time from Day 15 onwards, but it will be harder to see movement and pipping at first with the tiny eggs, compared with chickens. Just spread them out a bit, so long as they're not touching they'll be OK. Once they start to hatch the ones that haven't hatched yet will get all rolled around by the chicks but that doesn't matter. At this point you can up the humidity, and then close the incubator and don't open it again, whatever happens, (be strong!) until they have hatched and there has been 12-24 hours after the last one to hatch has emerged. Then move them to the brooder and perhaps leave any unhatched in there with it switched on for 48 hours, just in case. Don't be tempted to tidy up the eggshells.
Quails hatch easily because the shells on their tiny eggs are not very thick, unlike chicken eggs, so there should be no problems in the 'delivery room' but if you think one is having problems emerging, there's really nothing you can do and an assisted hatch would probably be fatal the the tiny chick and also opening the incubator would chill the others and drop the humidity. Did you watch the videos of mine hatching on my Ginnychick channel on YouTube? There's one bit where two newly hatched quails drag another out of its shell and give it a good going over, but it was OK.
If they go in today they should hatch over the weekend after next, maybe Sunday, possibly overnight to Monday.
