Climate-resilient shed design for extreme summers in Guntur and Tenali

Guntur and Tenali run hot from March to June, with weeks above 40°C and ground temperatures far higher. A desi bird handles heat better than a broiler, but not when it is crowded under a low asbestos sheet with no airflow. Most summer deaths in this belt are a building problem, not a disease problem.

The five decisions that matter most

• Orientation. Long axis east–west, so the roof does not take sun on a broad face all afternoon.
• Roof material. Asbestos and uninsulated metal are ovens. Thatched, tiled or double-layered sheet with an air gap runs many degrees cooler.
• Roof height. A ridge at 2.4–3 m gives hot air somewhere to rise. Low sheds trap it at bird level.
• Open sides with a ridge vent. Cross-ventilation, with an overhang that blocks direct sun while letting air through.
• Floor. Raised or well-drained, with dry litter. Damp floor plus heat is the worst combination.

Water is part of the design

Birds lose heat by panting, and panting costs water. A shed without adequate water points kills birds in exactly the hours you are not there. Two points per twenty birds, shaded, refreshed at least twice a day in summer, and never in direct sun.

A shallow pan or a wet gunny bag on the open side helps in the driest weeks; evaporative cooling does real work here even without a fan.

What a cheap, effective shed looks like

Practical specification for a small desi poultry shed in the Guntur belt

Element	Specification	Why
Footprint	3 m × 5 m for about 50 birds	Space per bird matters more in heat
Ridge height	2.4–3 m	Lets hot air rise above the birds
Roof	Thatch or double sheet with air gap	Cuts radiant heat
Sides	Open, wire mesh upper half, low wall below	Cross-ventilation with predator control
Floor	Raised 20–30 cm, dry litter	Drainage and dry litter
Overhang	60–90 cm	Shade without blocking breeze

Heat behaviour you can manage

• Feed early morning and late evening, not at midday. Birds eat less and digest less in heat.
• Reduce stocking density through the hot months; the same shed holds fewer birds in May than in December.
• Provide shade over the run, not just the shed — trees do this better than anything you can build.
• Watch for panting, wings held out, and birds crowding the water. Those are the warning signs that come before losses.
• Never move or handle birds in the afternoon heat. Do it at dawn.

The economics of getting it right

A shed that loses ten birds in May costs more than the difference between thatch and sheet. At ₹300–₹600 per kg live weight, ten birds is several thousand rupees, every year. The structural fixes are one-time.

This is also why the older sheds in the belt — low, thatched, shaded by trees — often outperform newer concrete ones. The design knowledge was already there.

Questions farmers ask about this

What roof is best for a poultry shed in Guntur heat?

Thatch, tiles, or a double-layered sheet with an air gap. Uninsulated asbestos or single metal sheet radiates heat down onto the birds and is the main cause of summer losses.

How tall should a country chicken shed be?

A ridge height of 2.4–3 metres with open sides and a ridge vent. Height lets hot air rise above bird level instead of trapping it.

How do I stop birds dying in a heatwave?

Shade over the run, water points refreshed twice daily and kept out of the sun, feeding at dawn and dusk, lower stocking density in summer, and never handling birds in the afternoon.
