Laying rate calculator
Enter eggs collected and hens in the flock — we compute Hen-Day rate and estimated annual production per hen.
verifiedFrom the team that has organised work on poultry farms for years.
Hen-Day % (against hens alive that day) is the standard indicator for day-to-day flock monitoring. Hen-Housed % (against hens placed at start) reflects the whole cycle result.
Enter to also get Hen-Housed %.
Leave at 1 for single-day data.

Indicative result based on breed curves (Aviagen Ross/Cobb, Aviagen Turkeys) and public factors. Real values depend on the flock and conditions. The calculator sends no data — it computes in your browser.
FAQ
What is the difference between Hen-Day and Hen-Housed?add
Hen-Day counts against hens alive today, so it rises with mortality at the same egg output. Hen-Housed always counts against hens placed at start and better reflects the whole-flock result.
What is a good laying rate?add
It depends on breed and stage — commercial layers typically peak at 90–95% HD, but compare against the specific strain’s production curve.
Can I calculate the rate over a longer period?add
Yes — enter total eggs and the number of days in the period, and the calculator accounts for it.
