Congrats! I don't know if there is any % chances here on whether she will continue or not. LOL Depends on the female. She might get off tomorrow, set until day 12 and get off or go full term!
You will have to wait and see if her hormones tell her exactly what to do. Since broodiness has been lost in most quail, this function in her body may or may not work properly to the very end. I would be ready with an incubator if you have one. AND a brooder. Some momma's don't have a clue as to what to do when chicks do hatch and have been known to even kill the chicks.
So just watch her carefully all the way through. I wouldn't disturb her at all. Remove all other birds so she can brood in peace. Keep all barking dogs away, no kid traffic, no night time predators.
Keep us posted!
