💡 Executive Summary: Building a Profitable Layer Farm
- High Production Potential: Commercial layer strains produce 290 to 320 eggs annually under proper management.
- Critical Brooding Phase: Maintain brooding temperatures of 33°C–35°C during week 1 to ensure flock uniformity and zero early chick mortality.
- Phase Feeding Strategy: Transition diets through Starter (20% CP), Grower (16% CP), Developer (14% CP), and Layer diets (17% CP + 3.8% Calcium for strong eggshells).
- Light Stimulation: Maintain 16 hours of light per day during laying to stimulate pineal gland hormone secretion for consistent oviposition.
1. Selecting the Right Layer Breed
The foundation of a successful egg production business starts with choosing high-performing layer chicken breeds tailored to your market demand and local climate conditions.
| Breed Type | Popular Strains | Egg Shell Color | Avg. Annual Eggs | Daily Feed Intake |
|---|---|---|---|---|
| White Egg Layers | Lohmann White, Hy-Line W-36, Isa White, Bovans White | White | 310 – 330 eggs | 105 – 110 grams / day |
| Brown Egg Layers | Isa Brown, Hy-Line Brown, Lohmann Brown, Babcock BV-380 | Brown | 295 – 315 eggs | 115 – 122 grams / day |
White egg layers are slightly lighter in body mass and exhibit higher feed conversion efficiency, making them popular for commercial egg processing. Brown egg layers are hardier and produce larger eggs that command a premium in retail consumer markets.
2. Chick Brooding Management (0 to 6 Weeks)
The brooding period covers the first 4 to 6 weeks of a chick's life when they cannot regulate their own body temperature. Proper brooding sets the flock's lifetime body weight uniformity and organ development.
A. Temperature Control Schedule
- Week 1 (Days 1–7): 33°C to 35°C (91°F to 95°F)
- Week 2 (Days 8–14): 30°C to 32°C (86°F to 89°F)
- Week 3 (Days 15–21): 27°C to 29°C (80°F to 84°F)
- Week 4 (Days 22–28): 24°C to 26°C (75°F to 79°F)
- Week 5+: 21°C (70°F) ambient temperature
Observe chick behavior under the brooder stove: if chicks crowd tightly under the heater, they are cold; if they spread far to the edges panting, they are hot. Uniform distribution across the brooding ring indicates optimal comfort.
3. Layer Vaccination & Biosecurity Schedule
Infectious disease outbreaks can permanently drop egg production or cause high flock mortality. A standard commercial layer vaccination program includes:
| Age | Target Disease | Vaccine Type & Route |
|---|---|---|
| Day 1 (Hatchery) | Marek's Disease & Infectious Bronchitis (IB) | Subcutaneous Injection & Spray |
| Day 7 | Newcastle Disease (ND - Ranikhet) + IB | Eye Drop / Drinking Water |
| Day 14 | Infectious Bursal Disease (IBD - Gumboro) | Drinking Water |
| Week 6 | Fowl Pox | Wing Web Puncture |
| Week 14 | ND + IB + Egg Drop Syndrome (EDS) Booster | Injected Oil Emulsion (Killed) |
4. Phase Feeding & Nutritional Requirements
Layer hens require precise nutritional transitions to support rapid skeletal growth during the grower stage and shell formation during laying.
- Chick Starter (0–8 Weeks): 20% Crude Protein (CP), 2,900 kcal/kg ME, 1.0% Calcium. Promotes organ and frame growth.
- Grower Diet (9–15 Weeks): 16% CP, 2,750 kcal/kg ME, 1.0% Calcium. Prevents early onset of obesity while building bone density.
- Pre-Lay Diet (16–17 Weeks): 17% CP, 2.5% Calcium. Prepares the medullary bone for calcium storage prior to first egg.
- Layer Phase 1 (18–45 Weeks): 17.5% CP, 3.8%–4.0% Calcium, 0.45% Available Phosphorus. Supports peak egg production and shell synthesis.

Egg production begins around 18 to 20 weeks, reaching peak production at 26 to 30 weeks. Maintaining egg quality requires:
- 16-Hour Photoperiod: Provide 16 hours of continuous light (daylight + artificial LED bulb supplementation at 30 lux) to maintain ovarian stimulation. Never decrease day length during the laying cycle.
- Coarse Limestone / Oyster Shells: Provide 60% of dietary calcium in coarse particle size (2–4 mm) in the evening feed so calcium is digested slowly overnight when the eggshell is being deposited in the shell gland.
- Clean Nest Boxes & Egg Handling: Collect eggs at least 3 times daily to prevent cracking and cannibalism. Store eggs in a cool room at 13°C to 15°C (55°F–59°F) with 75% relative humidity.
6. Frequently Asked Questions (FAQ)
Q: At what age do layer chickens start laying eggs?
Healthy commercial layer hens typically begin laying eggs at 18 to 20 weeks of age, reaching peak production (over 90% lay rate) between 26 and 32 weeks.
Q: How many eggs does a layer hen produce per year?
Well-managed commercial layer strains (such as Isa Brown or Hy-Line) produce approximately 290 to 320 eggs during their primary 52-week laying cycle.
Q: What temperature is required for brooding day-old layer chicks?
Day-old chicks require a brooding temperature of 33°C to 35°C (91°F to 95°F) during their first week, reduced by 2.5°C (5°F) each week until reaching 21°C (70°F) at week 4.
