Layer egg production, HDP and HHP calculator.
Calculate hen-day and hen-housed egg production, dozens produced and feed per dozen eggs.
Layer egg production, HDP and HHP inputs
Planning tool only. Space allowance, breed performance, ventilation, lighting, welfare, vaccination, medicine, feed formulation and local regulations require qualified poultry-management advice and daily farm monitoring.
Method: HDP divides eggs by live hens; HHP divides eggs by hens originally housed. Feed per dozen divides total feed by eggs divided by twelve.
Inputs used: Live hens today = 950; Eggs collected today = 850; Hens originally housed = 1,000; Feed consumed today = 105 kg
Assumptions: The result uses the values, units and options shown in the input snapshot.
Scope and warnings: Planning tool only. Space allowance, breed performance, ventilation, lighting, welfare, vaccination, medicine, feed formulation and local regulations require qualified poultry-management advice and daily farm monitoring. Rounding and excluded real-world terms can make an external result differ.
How this layer egg production, hdp and hhp calculator works
HDP divides eggs by live hens; HHP divides eggs by hens originally housed. Feed per dozen divides total feed by eggs divided by twelve.
A worked example
850 eggs from 950 live hens gives 89.47% hen-day production.
Why are HDP and HHP different?
HDP uses birds alive today, while HHP retains the original housed count. Both are useful when interpreted with mortality and flock-age records.

Record live hens and original housed hens separately
Hen-day production uses today’s live hens; hen-housed production retains the starting flock. Using both makes mortality and laying performance easier to distinguish.
Feed per dozen depends on the feed and egg count from the same day. Shell quality, rejects, flock health and egg grading need separate records.
