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

What each input means

Species
Select species: 1 = Chicken (21 days), 2 = Duck (28 days), 3 = Turkey (28 days), 4 = Goose (30 days), 5 = Quail (17 days).
Set Date (Day of Year)
Day of year eggs are set in the incubator (1 = Jan 1, 60 = Mar 1, 121 = May 1).

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    Species = 1, Set Date (Day of Year) = 60 = 2 input(s) provided
  2. Calculate Incubation Period
    Incubation Period = sp.days
    21 = 21
  3. Calculate Expected Hatch Date
    Expected Hatch Date = dayOfYearToDate(hatchDayOfYear)
    Mar 22 = Mar 22
  4. Calculate Species
    Species = sp.name
    Chicken = Chicken
  5. Calculate Lockdown Date
    Lockdown Date = dayOfYearToDate(lockdownDayOfYear)
    Mar 19 = Mar 19
