How to Use This Calculator

Select the species: 1 = chicken, 2 = duck, 3 = turkey, 4 = goose, or 5 = quail.
Enter the set date as the day of year (1–365) when eggs were loaded into the incubator.
Review Setting Temperature, Setting Humidity, and Lockdown Temperature/Humidity for your incubator settings.
Note the Expected Hatch Date and Lockdown Date — move eggs to the hatcher and stop turning at lockdown.
Follow the turning schedule during the setting phase — eggs should be turned at least 3 times per day.
