The last 3 to 4 days of incubation are referred to as ‘lockdown.’ During the lockdown phase of incubation, you will stop turning the eggs and increase the incubator’s humidity to 65%. Keep reading: Common causes of poor hatch rates Lockdown and hatching day Dead embryos stop growing, which means they will often be smaller than other, live embryos that have incubated the same length of time. When an embryo dies, the veins may quickly break down, leaving only a motionless dark mass inside of the egg. If your chick has died, there will be no movement. You should also see a network of veins spreading outward from the embryo. If your chick is alive, at 10 days you should see the embryo, a dark, formless mass, rocking back and forth in the egg. Quail eggs are spotted and difficult to see into, but the principles are largely still the same. You will also likely have eggs that started developing but quit at some point during incubation. Eggs which did not develop will light up and appear clear. Eggs with development will be darker, and you may be able to see movement and veins inside of the egg. It should be pretty apparent which eggs have developed and which have not. This can be extraordinarily difficult to clean out of your incubator and it can spread the bacteria to all of the eggs, potentially killing everyone inside.

It also prevents oils from your hands from being deposited on the eggs, where they can block the egg’s pores.
