Work out poultry housing space instantly with clear inputs, formula shown and shareable results.
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.
Housing space
Floor area = birds x space per bird; house length = area / width
Feeder space
Feeder length (m) = birds x cm per bird / 100
Maximum stocking densities and welfare requirements are set by law in many jurisdictions. Check the applicable code before finalising a house design.
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.
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.
