how long coturnix chicks can stay in incubator after hatch?

its my first incubation ever, and i have coturnix eggs and chicken eggs. coturnix started to pip 9-10 hours ago, and first chicken cracked the shell maybe 1 hour ago.. how long coturnix chicken can stay in bator after hatch? they are hatching slowly, few of them are 8-9 hours inside after hatch, the rest is still hatching, so i don't know- should i take them out or not, those dry ones. I'm afraid that opening incubator wide to take out those chicks will affect the hatch od others, but i'm afraid too that little ones will be hungry and thirsty. I know chicken chicks can stary 24-48 hours after hatch without food but coturnix chicks? anyone can tell me?
