Layer Chicken Production Costs and Returns in Kenya (2025/2026): A Data-Driven Guide
Introduction: Why Layer Farming is a Profitable Agribusiness
Layer chicken farming remains one of the most lucrative agribusiness ventures in Kenya, driven by consistent demand for eggs and poultry meat. With urbanization and population growth, the market for eggs has expanded significantly, with prices stabilizing at KSh 280 per tray (30 eggs) in major markets like Nairobi and Mombasa in 2025/2026 [1]. For smallholder and commercial farmers, understanding the costs and returns is critical to profitability. This guide breaks down startup costs, feeding expenses, revenue projections, and risk mitigation strategies using 2025/2026 market data.
Startup Costs for 50, 200, and 300 Birds
Startup costs vary based on flock size, infrastructure, and sourcing strategies. Below are detailed breakdowns for three common flock sizes, using data from Secret Layers and Bizna Kenya (2025/2026 prices):
50-Bird Setup
Day-old chicks : 50 x KSh 120 = KSh 6,000 Chick mash (0–8 weeks) : 2.5 kg/bird x KSh 40/kg = KSh 5,000 Grower mash (9–18 weeks) : 3 kg/bird x KSh 35/kg = KSh 5,250 Layer mash (19+ weeks) : 3.5 kg/bird/week x 80 weeks = KSh 49,000 Housing : Basic coop (existing structure) = KSh 5,000 Equipment : Feeders, waterers, lighting = KSh 10,000 Vaccinations : KSh 150/bird = KSh 7,500 Labour : Part-time = KSh 3,000/month
Total Startup Cost : ~KSh 85,750
200-Bird Setup
Day-old chicks : 200 x KSh 120 = KSh 24,000 Chick mash : 200 x 2.5 kg x KSh 40 = KSh 20,000 Grower mash : 200 x 3 kg x KSh 35 = KSh 21,000 Layer mash : 200 x 3.5 kg x 80 weeks = KSh 196,000 Housing : Reinforced coop = KSh 25,000 Equipment : Feeders, waterers, lighting = KSh 25,000 Vaccinations : 200 x KSh 150 = KSh 30,000 Labour : Full-time = KSh 10,000/month
Total Startup Cost : ~KSh 331,000
300-Bird Setup
Day-old chicks : 300 x KSh 120 = KSh 36,000 Chick mash : 300 x 2.5 kg x KSh 40 = KSh 30,000 Grower mash : 300 x 3 kg x KSh 35 = KSh 31,500 Layer mash : 300 x 3.5 kg x 80 weeks = KSh 294,000 Housing : Medium-sized coop = KSh 50,000 Equipment : Feeders, waterers, lighting = KSh 35,000 Vaccinations : 300 x KSh 150 = KSh 45,000 Labour : Full-time + part-time = KSh 15,000/month
Total Startup Cost : ~KSh 526,500
Note: Prices are based on Secret Layers and Bizna Kenya (2025/2026) and may vary by region.
Feed Cost Analysis: The 70–80% Rule
Feed constitutes 70–80% of total production costs in layer farming. Here’s a breakdown for 300 birds:
Chick mash (0–8 weeks) : 300 x 2.5 kg = 750 kg x KSh 40 = KSh 30,000 Grower mash (9–18 weeks) : 300 x 3 kg = 900 kg x KSh 35 = KSh 31,500 Layer mash (19–80 weeks) : 300 x 3.5 kg x 80 weeks = 84,000 kg x KSh 40 = KSh 3,360,000
Total Feed Cost : ~KSh 3,421,500 over 80 weeks
This aligns with findings from the Kenya Livestock Producers Association , which reports similar feed cost structures for 200-bird setups.
Revenue Projections: How Much Can You Earn?
Revenue depends on egg production rates, tray prices, and market access. Assuming 80% production efficiency and a 5% mortality rate:
300-Bird Revenue
Daily egg output : 300 x 80% = 240 eggsTrays sold/day : 240 ÷ 30 = 8 trays Daily revenue : 8 x KSh 280 = KSh 2,240 Monthly revenue : KSh 2,240 x 30 = KSh 67,200 Annual revenue : KSh 67,200 x 12 = KSh 806,400
500-Bird Revenue
Daily egg output : 500 x 84% = 420 eggsTrays sold/day : 14 traysDaily revenue : 14 x KSh 280 = KSh 3,920 Annual revenue : KSh 3,920 x 365 = KSh 1,430,800
Note: Prices may vary by region and season. For example, prices in rural areas may drop to KSh 250/tray, while Nairobi markets can reach KSh 320/tray.
Profit Calculations: Is Layer Farming Worth It?
Let’s calculate profits for a 300-bird setup:
Total revenue (18 weeks) : 8 trays/day x KSh 280 x 126 days = KSh 282,240 Total costs (18 weeks) : Feed (KSh 3,421,500 ÷ 80 weeks x 18) + Labour (KSh 15,000 x 1.5 months) = ~KSh 126,000 + KSh 22,500 = KSh 148,500 Profit : KSh 282,240 - KSh 148,500 = KSh 133,740
For 100 birds:
Monthly profit : ~KSh 1,600 (based on KSh 2,240 revenue - KSh 640 feed + other costs)
Common Challenges and Risk Mitigation
Mortality and Disease : A 5% mortality rate (as in the Uganda manual) can reduce profits by 15–20%. Mitigate with biosecurity and regular vaccinations.Feed Price Volatility : Lock in prices with suppliers or grow feed crops like maize and legumes.Market Access : Partner with local supermarkets or join cooperatives to secure steady buyers.Labour Shortages : Use automated feeding systems or train family members to reduce dependency on hired labor.
Conclusion: Key Strategies for Success
Optimize feed costs by sourcing from bulk suppliers like Bizna Kenya.Monitor production rates weekly to identify health or management issues.Diversify income streams by selling manure (KSh 500/bag) or cull birds (KSh 250/bird).
