Weather/Climate Adaptive Housing Design

The A-Frame or Open-Sided Philosophy

In tropical climates, the best turkey house is usually an open-sided structure with wire mesh walls.

• The 3-Foot Wall: Build a solid wall (stone, timber, or iron sheets) up to 3 feet (about 1 meter). This prevents ground-level drafts from hitting the birds directly.

• The Mesh Upper: Above the 3-foot wall, use a strong galvanized wire mesh (chicken wire is often too weak for predators; use chain-link or heavy-gauge mesh). This allows the hot air and ammonia from bird droppings to escape.

• The Curtain System: Use old gunny bags (shamba sacks) or heavy plastic sheets that can be rolled up during the day and dropped down at night to keep the birds warm.

The Floor: Your Foundation for Profit

A turkey that cannot walk cannot eat, and a turkey that doesn’t eat is a loss. Because these birds reach 15kg+, their legs are under immense pressure.

• Concrete vs. Earth: A concrete floor is easier to disinfect, but a well-compacted earth floor can work if managed well.

• The 10cm Rule: You must use at least 10cm (4 inches) of deep litter – preferably wood shavings (not sawdust). Sawdust is too fine; turkeys might eat it and get “impacted” (constipated), and it holds moisture which causes “bumblefoot” (painful foot sores).

• Dryness is King: If the litter gets wet around the waterers, remove it immediately. Wet bedding releases ammonia, which burns a turkey’s eyes and lungs.

Orientation: Following the Sun

In Africa, always build your house in an East-West orientation.

• Why? This ensures that the hot midday sun hits the roof, not the open sides of the house. If the sun shines directly into the house, the birds will huddle in the shade, overheat, and stop growing.

• The Overhang: Ensure your roof has a wide overhang (at least 2 feet) so that when it rains, the water doesn’t splash into the house and soak the bedding.

Case Study: Mwangi’s Cool Coop in Thika

Mwangi noticed his turkeys were panting heavily (a sign of heat stress) every afternoon. His house had a low iron sheet roof that acted like an oven. Instead of rebuilding, he painted the roof white to reflect the sun and planted sunflowers and matura trees on the western side of the building to provide natural shade. His birds immediately became more active, and his mortality rate dropped by 8% because they were no longer stressed by the heat.

Important Things to Keep in Mind

• Security: Turkeys are expensive. Ensure your doors have strong locks and the mesh is buried 30cm into the ground to stop digging predators like honey badgers.

• Ammonia Test: If you walk into the house and your eyes sting or you can smell choking air, your ventilation is failing. Open the curtains.

• The Heavy Factor: Everything in a turkey house must be heavy-duty. Weak perches will snap under the weight of a mature Tom.
