How to Successfully Rear 100 Improved Kienyeji Chickens Starting from One-Month-Old Chicks

 Rearing improved Kienyeji chickens has become a popular and profitable venture across Kenya. These hardy birds are well-suited for both meat and egg production, and starting with one-month-old chicks reduces your risk as a beginner because you skip the delicate brooding stage.

In this guide, we will walk you through everything you need to know to start and manage a flock of 100 improved Kienyeji chickens from the age of four weeks onward. This plan is beginner-friendly and focuses on practical, cost-effective methods suitable for small to medium-scale poultry farming.

Project Objectives

• Rear 100 improved Kienyeji chickens for egg and meat production.

• Begin with one-month-old chicks, avoiding the brooding phase.

• Implement a semi-intensive system combining shelter and open space.

• Minimize mortality, maximize productivity, and achieve profitability within 6 to 8 months.

Step 1: Housing Setup and Site Preparation

Before bringing in your chicks, it is critical to set up proper housing to protect them from predators, bad weather, and disease.

Space Requirements

• Indoor space: Allow at least 1.5 to 2 square feet per bird, which equals about 150 to 200 square feet for 100 chickens.

• Outdoor run: Provide 1 to 1.5 square meters per bird for daytime access, which translates to 100 to 150 square meters.

Basic Poultry House Features

• Well-ventilated, preferably three sides open with wire mesh.

• Corrugated iron sheets for roofing.

• Floor should be concrete or compacted soil, covered with dry wood shavings.

• Nesting boxes (10 to 15 units) for laying hens.

• Roosting bars inside the coop for chickens to perch at night.

• Secure perimeter with chicken wire or netting.

Hygiene and Biosecurity

• Disinfect the structure with Jik or Virkon before the chickens arrive.

• Ensure water and feeders are clean and raised slightly off the ground to avoid contamination.

• Create a footbath at the entrance with disinfectant.

Step 2: Receiving Your Chicks

When you receive the one-month-old chicks, they will be about 4 weeks old and past the brooding stage.

What to Do on Arrival

• Transport chicks early morning or late evening to avoid heat stress.

• Provide immediate access to clean drinking water, preferably with multivitamins or glucose to ease transition stress.

• Observe for signs of stress, sickness, or injuries.

• Provide them with Growers Mash and ensure comfortable bedding and warmth if the weather is cold.

Step 3: Feeding Program (4 Weeks to Maturity)

Feeding is one of the most critical components of poultry farming. The right nutrition ensures healthy growth, strong immunity, and high productivity.

Feeding Guide

Age Range	Feed Type	Protein Content	Daily Amount per Bird
4–8 weeks	Growers Mash	18–19%	60–80 grams
9–20 weeks	Growers Mash	17–18%	80–100 grams
20 weeks onward	Layers Mash	16–18%	100–120 grams

Supplementary Feed (Optional but Recommended)

• Crushed maize and omena (fishmeal) for protein.

• Sukuma wiki, cabbage leaves, ugali leftovers for vitamins.

• Crushed eggshells or small stones to act as grit for digestion.

• Ensure clean, fresh water is always available and changed at least twice daily.

Total Feed Estimate

Each bird will consume about 8 to 10 kg of feed from 4 weeks to 6 months, amounting to 800 to 1,000 kg total for 100 birds. Budget around KSh 30,000 to KSh 40,000 for this quantity.

Step 4: Health and Vaccination Schedule

While improved Kienyeji chickens are hardy, they still require basic vaccination and deworming to stay healthy and productive.

Vaccination Program

Age (Weeks)	Vaccine	Purpose
Week 4–5	Gumboro Booster	Intestinal disease prevention
Week 6	Fowl Pox	Viral disease, skin protection
Week 8	Newcastle (Lasota)	Viral respiratory disease
Monthly	Deworming	Internal parasite control

General Health Practices

• Give vitamins weekly through water to boost immunity.

• Observe for common signs of illness: droopy wings, diarrhea, poor appetite, or coughing.

• Isolate any sick birds immediately.

Step 5: Transition to Laying and Production Phase

From week 20 onwards, the hens will begin laying eggs. Egg production starts slowly but increases to a peak of about 80–90 percent laying rate.

Expected Egg Production

• 200 to 250 eggs per hen annually under good management.

• From 80 hens (after accounting for cockerels and mortality), expect 1,200 to 1,600 eggs per month at peak.

Income Potential

• If eggs are sold at KSh 15 each, you could earn KSh 18,000 to KSh 24,000 per month.

• Additional revenue can come from selling cockerels for meat at KSh 500 to KSh 700 each after 5 to 6 months.

• Chicken manure can be sold or used in farming.

Estimated Budget

Item	Quantity/Details	Cost Estimate (KSh)
Chicks (100)	One-month-old	120–150 per chick = 12,000–15,000
Poultry Housing	Timber, mesh, roofing	15,000–30,000
Feed (first 5 months)	800–1,000 kg	30,000–40,000
Feeders and Drinkers	4–5 each	3,000–5,000
Vaccines & Vitamins	As per schedule	2,000–3,000
Miscellaneous	Transport, tools	2,000

Total Estimated Startup Cost: KSh 64,000 to KSh 95,000

Tips for Beginners

• Always buy your chicks from a reputable hatchery or farm.

• Keep a simple daily routine: feeding, watering, cleaning, and observation.

• Start small, monitor performance, and scale gradually.

• Record expenses, feed use, egg production, and sales for better management.

• Join local poultry groups or cooperatives for support and bulk discounts on feed or vaccines.
