I have left chickens in the incubator for 12 hours after they hatch and they are fine. How long can Coturnix quail stay in the incubator after hatching before they suffer from thirst or starvation. I like to leave my birds in the incubator until I do not see any piping or zipped eggs and then I take everyone that hatched out and replace the top quickly. I don't want anybody getting stuck in the egg from a loss in humidity so I wait until the incubator looks likes a big ball of fluff inside and remove them then. I just don't know if quail can survive this like chickens do.
