Sample Schedule (First 2 Weeks)
House Preparation
Construct or clean a simple housing structure (mud, timber, or iron sheets). Allow 0.25 m² per bird. Ensure good ventilation, predator-proof wire mesh, perches at 40 cm height, and nesting boxes (1 per 5 hens).
Source Day-Old Chicks
Purchase KARI Improved Kienyeji or Rainbow Rooster chicks from certified hatchery (e.g., Kenchic, Muguku, or KARI). Avoid unknown sources to ensure genuine genetics.
Chick Brooding Setup
Prepare brooder with 60W bulb per 20 chicks. Temperature: 32 °C at chick level. Provide chick mash or crushed maize with omena (dagaa) powder (15% protein) for first 2 weeks.
Newcastle Vaccination
Vaccinate against Newcastle Disease using Lasota strain eye-drop method. Kienyeji chickens have lower natural resistance to Newcastle than pure locals — vaccination is essential.
Introduce Local Supplementary Feed
Gradually introduce local feed: whole maize (50%), sunflower/soybean meal (20%), omena (10%), sorghum (10%), bone meal (5%), salt (1%), minerals (4%). This is cost-effective and achieves 15–18% protein.
Gumboro Vaccine
Administer IBD (Gumboro) vaccine in drinking water. This disease causes immunosuppression and is fatal in chicks; it is often confused with Newcastle by farmers.
