Model commercial layer hen production and daily egg revenue. Enter your flock size, hen-day laying percentage, cracked/rejected egg rate, and wholesale tray prices to calculate daily, weekly, and monthly egg outputs and net farm profits.
The Egg Production Calculator applies standard avian zootechnical mathematics calibrated specifically for Pakistani poultry production norms. Whether modeling 35-day Cobb 500 broilers in Punjab or commercial brown layers in KPK, the engine accounts for feed intake curves, bird mortality, utility overheads, and prevailing mandi price mechanics.
📐Egg Output & Revenue Formulas
Gross Eggs Per Day = Total Layer Hens × (Hen-Day Laying % ÷ 100)
Saleable Eggs Per Day = Gross Eggs × (1 − (Rejected % ÷ 100))
Daily Trays Produced = Saleable Eggs ÷ 30 (Standard Pakistan Egg Tray)
Daily Dozens Produced = Saleable Eggs ÷ 12
Daily Egg Sales Revenue (Rs) = Daily Trays × Price Per Tray (or Dozens × Price Per Dozen)
Daily Feed Cost (Rs) = Layer Hens × (Daily Feed Intake in Grams ÷ 1,000) × Feed Price Per kg
Daily Net Profit (Rs) = Daily Revenue − Daily Feed Cost − Other Daily Expenses
Monthly Estimated Profit (Rs) = Daily Net Profit × 30
Worked Example: Step-by-Step Practical Calculation
Scenario: A commercial layer farm in Chakwal houses 5,000 Lohmann Brown hens operating at 92% peak hen-day production, with 1.5% broken/rejected eggs.
Starting Assumptions:
Active Layer Hens: 5,000
Hen-Day Laying %: 92% (Peak lay)
Broken/Rejected Eggs: 1.5%
Egg Price: Rs. 6,600 per crate/box (Rs. 550 per 30-egg tray, or ~Rs. 18.33/egg)
Daily Feed Intake: 115 grams per hen @ Rs. 145/kg feed
Frequently Asked Questions
Common questions about Egg Production Calculator
Hen-day production percentage is the standard measure of layer flock efficiency, calculated as (Number of eggs laid in 24 hours ÷ Number of live hens housed on that day) × 100. Commercial flocks peak at 92%–96% between weeks 25 and 35.
In Pakistan's wholesale egg mandis, eggs are packed in moulded pulp trays containing 30 eggs each. A commercial wholesale cardboard box or wooden crate holds 12 trays, totaling 360 eggs (30 dozen).
Extreme heat above 35°C triggers heat stress in laying hens, reducing feed intake and blood calcium availability. This causes egg production drops of 10%–25% and leads to thin-shelled, cracked, or misshapen eggs with higher breakage rates.
The leading commercial layer breeds in Pakistan include Lohmann Brown, Hy-Line Brown, Novogen Brown, and Bovans White. Brown egg layers are preferred by retail consumers in Punjab and KPK.
Commercial layer hens begin laying at approximately 18 to 20 weeks of age and remain in profitable production until 72 to 80 weeks of age, after which they are culled and sold to the spent hen (Desi Murghi substitute) meat market.
Poultry Farming Estimation Notice:
These calculations are estimates provided for informational and planning purposes. Actual poultry farming costs, feed performance, Feed Conversion Ratios (FCR), mortality, mandi market prices, and net profitability vary depending on farm shed ventilation, bird genetics, feed quality, seasonal temperatures, management practices, and local market conditions across Pakistan. Always verify binding commercial transactions with registered wholesale mandi dealers or local District Market Committees.
