My incubator has decent circulation and my baby quail appear to dry out reasonably quick. I have had only small amounts in lockdown at a time (around 8-15 eggs). I wait 12 hours after the last egg has hatched before I move them to the brooder. I removed the unhatched eggs about 2 days after moving the bulk of them to the brooder. Maybe, about 72 hours after first egg hatched. I haven't lost a bird in the brooder, yet.
