You can but you are still going to need to open the incubator to turn eggs.
Technically lockdown is just the time you stop turning, don't open your incubator too much, and raise your humidity.
How many pheasant eggs are in your incubator?
Can you just hand turn the pheasant eggs every day, at least twice a day or more?
Every time you open the incubator just fill up your waters again to keep the humidity up.
