Work out egg production rate instantly with clear inputs, formula shown and shareable results.
Divides eggs collected by hen-days to give the hen-day production rate, the standard laying flock performance measure.
Hen-day production
Rate (%) = eggs collected / (hens x days) x 100
Commercial layers peak above 90% hen-day production and average 75 to 85% across a laying cycle.
It uses the original number housed as the denominator, so mortality lowers it while hen-day production ignores it.
