Egg Production Calculator

Quick answer

Eggs/day = hens × lay%.

  • Flock egg output at 85–90% lay with feed per dozen (1.55–1.70 kg) and monthly dozens from hen numbers.

How the Egg Production Calculator Works

Daily Eggs = Number of Hens × (Lay Rate / 100)

This calculator estimates egg production based on flock size and laying rate. Commercial hens typically lay at 80-95% rate during peak production, declining over time.

  1. 1

    Step 1

    Enter the total number of laying hens

  2. 2

    Step 2

    Input the current or expected laying rate percentage

  3. 3

    Step 3

    Enter your selling price per dozen eggs

  4. 4

    Step 4

    Review daily, monthly, and annual egg production

  5. 5

    Step 5

    See estimated annual revenue projections

Use Cases

Planning egg inventory and sales schedules

Evaluating flock productivity and efficiency

Calculating break-even points for layer operations

Deciding optimal flock replacement timing

Tips

  • 1

    Peak production (90%+) occurs at 25-35 weeks of age

  • 2

    16 hours of light daily optimizes laying rate

  • 3

    Laying rate naturally declines 10-15% annually after peak

  • 4

    Molt can be induced to extend productive life

  • 5

    Free-range eggs can command 50-100% premium prices

Common Mistakes

  • Expecting peak production rates throughout the year

  • Not planning for seasonal laying rate drops

  • Ignoring feed-to-egg conversion ratios in cost analysis

  • Underestimating egg breakage and cull rates

FAQs

How many eggs does a hen lay per year?

Commercial laying hens produce 280-320 eggs in their first year. Production declines about 10-15% each subsequent year. Heritage breeds typically lay 150-250 eggs annually.

What is a good laying rate?

Commercial operations target 90-95% during peak production (25-35 weeks). Rates of 80% are still profitable. Below 65-70%, hens may be candidates for replacement.

When do hens start laying?

Most commercial breeds start laying at 18-22 weeks of age, reach peak production at 25-35 weeks, and remain productive for 18-24 months before significant decline.

How does light affect egg production?

Hens need 14-16 hours of light daily for optimal production. As days shorten in fall, supplemental lighting maintains laying rates. Sudden light changes can cause stress and production drops.
