I have a lot of different eggs in my sportsman incubator, ducks 2 types of quail, guineas, pheasants, bantams and regular chickens. All have different hatch dates. What is the importance of lockdown. How often do you clear chicks? We've had quail hatch for 7 days straight off the same batch! I heard that you can take the bottom tray out and keep the turner running while you're hatching other eggs?
