Layers · 500,000 hens · enriched colony
500,000-hen layer farm — Egypt
Illustrative scenario: 5-house enriched colony layer farm feeding a shell-egg packing center. Sourcing covered A-frame colony cages, manure belts, egg-belt collection and central climate control.

125 m³/day
Feed consumption
55 t/day at peak lay
Egg output
460,000 eggs/day at peak
Manure output
38 t/day wet basis
System design choices
Why each subsystem was specified the way it was.
| Area | Choice | Rationale |
|---|---|---|
| Housing | 8-tier enriched colony, A-frame | Maximizes hens per m² while meeting perch/scratch/nest requirements for export retailers. |
| Manure handling | Belt with cross-conveyor + drying tunnel | Reduces ammonia <20 ppm and produces 55% DM manure for direct field application. |
| Egg collection | Longitudinal + elevator to central packer | Single grading line for 5 houses cuts labor 40% vs decentralized collection. |
| Ventilation | Cross + tunnel hybrid with 4″ pad | Cross ventilation for winter minimum rate; tunnel + pad for 40 °C summer peaks. |
| Lighting | Dimmable LED, warm-white 2700K | Programmable step-up lighting supports 16 h photoperiod at 20–30 lux. |
