Hatchery Egg Setting Calculator

Work out hatchery egg setting instantly with clear inputs, formula shown and shareable results.

About Hatchery Egg Setting Calculator

Chick output is eggs set x fertility x hatch of fertile x saleable percentage. Working backwards, eggs to set is the chick requirement divided by that combined yield. Hatch of total eggs set — fertility times hatch of fertile — is the number that matters commercially, typically 80-85% in a well-run hatchery.

Formulas

Hatchery yield

Overall yield = fertility % x hatch of fertile % x saleable %

Eggs to set

Eggs to set = chicks required / overall yield

Worked example

With the default values below, Hatchery Egg Setting Calculator returns Eggs To Set of 12,734. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

  • The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

What drives fertility down?

Breeder flock age, male-to-female ratio, mating activity, nutrition and heat stress. Fertility falls steadily after about 45 weeks of breeder age.

Does egg storage affect hatchability?

Yes. Hatchability falls roughly 0.5-1% per day of storage beyond four days, and pre-storage incubation or turning is needed for longer holds.
