Poultry Housing Space Calculator

Work out poultry housing space instantly with clear inputs, formula shown and shareable results.

About Poultry Housing Space Calculator

Floor area is birds x space per bird — around 0.09 m2 for a broiler to 2 kg, 0.14-0.19 m2 for a layer on deep litter. Feeder and drinker space are separate constraints: birds that cannot all reach feed at once show uneven growth regardless of how much floor they have.

Formulas

Housing space

Floor area = birds x space per bird; house length = area / width

Feeder space

Feeder length (m) = birds x cm per bird / 100

Worked example

With the default values below, Poultry Housing Space Calculator returns Floor Area Required of 450.00. 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 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.
Maximum stocking densities and welfare requirements are set by law in many jurisdictions. Check the applicable code before finalising a house design.

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

Frequently Asked Questions

Is density better expressed in kg per m2?

Yes for broilers — welfare codes commonly cap 33-39 kg/m2 at depletion. A fixed area per bird only works if the target live weight is fixed too.

What about ventilation?

Density and ventilation are linked. High density needs proportionally more air exchange to remove heat, moisture and ammonia; without it, litter goes wet and footpad lesions follow.
