Housing, shed design and equipment for small flocks
Domain 2 – Housing, shed design and equipment for small flocks
The exam tests site selection, shed orientation, floor space, ventilation, litter management and the equipment needed for a small backyard or semi-commercial flock in hot, humid Odisha.
Core rules
- Site: high, well-drained land, away from dwellings and standing water, easy road access, shade from trees on the west side. Orient the shed east–west to reduce direct sun on the long wall.
- Floor space: about 1 sq ft per adult bird in deep litter; allow 2–3 sq ft per bird in backyard scavenging systems; brooder space is much less (about 0.5 sq ft per chick). Overcrowding causes wet litter, cannibalism and disease.
- Ventilation: ridge ventilation and open sides with wire mesh; avoid drafts on chicks. In humid weather, air movement matters more than warmth for adult birds.
- Floor and litter: raised floor or concrete base; 5–8 cm of dry paddy husk, sawdust or chopped straw; stir litter daily and replace wet patches.
- Equipment: linear feeders (about 4–5 cm/bird), waterers, nest boxes (1 per 5 hens), perches, brooder, footbath and a feed store.
Worked example
Plan a shed for 50 adult birds under deep litter. At 1 sq ft/bird, minimum floor area = 50 sq ft. Add 20% for feeders, nest boxes and working space = 60 sq ft. A 10 ft × 6 ft shed gives exactly 60 sq ft. If the same 50 birds were kept in a backyard scavenging system at 2.5 sq ft/bird, the required area would be 125 sq ft, so the 10 × 6 ft shed would be too small.
Traps
- Using broiler floor-space figures for adult layers.
- Building on low ground that floods in the monsoon.
- Closing side walls “to keep warm” and causing ammonia build-up.
- Placing waterers under perches so litter stays wet.
Key points
- Choose high, well-drained land and orient the shed east–west.
- Allow about 1 sq ft/bird in deep litter; more in scavenging systems.
- Ventilation and dry litter prevent ammonia and disease.
- Provide feeders, waterers, nest boxes and perches at correct space allowances.
- Wet litter is a warning sign of overcrowding or poor drainage.
