Well.. For now, it's probably more of a big 'IF'. But, should you get near hatching date and she is still on the eggs, I'd keep a very close eye on her. If they are on wire or the cage is otherwise unsuited for chicks, I'd remove her after the chicks hatch. If the cage is okay for chicks, I'd remove the other quail as soon as I see a chick or empty egg shell. I might do this even if I decided on removing the mother and chicks actually, to make sure the chicks that hatch first aren't hurt by the other quail while the rest of the chicks hatch. I think the sound of the hatched chicks will keep her broody no matter what changes you do, but she might still abandon a nest of pipped eggs if one or more chicks hatch before the rest.
