Layer housing systems
Cage Systems
Cage systems house commercial layers in tiered structures with automated feed, water, egg-collection and manure-belt handling. Conventional cages are being phased out in the EU and some other jurisdictions; enriched (furnished) cages remain accepted in many markets.

Role within the project
Cage systems maximise birds per m² and mechanisation of egg collection and manure handling. The trade-off is welfare regulation exposure and export-market constraints.
Typical applications
- Conventional cage systems (declining, market-restricted)
- Enriched / furnished cage systems
- High-rise and manure-belt cage layouts
Selection criteria
- Compliance with target-market welfare rules
- Stack height compatible with house clearance
- Egg-belt cracked-egg data at commercial throughput
- Manure-belt drying and export handling
Engineering considerations
- Floor flatness ±3 mm/3 m for high stacks
- Manure-belt slope and aeration for pre-drying
- Ventilation profile per tier — top tier receives most air
- Emergency drop-side and standby feed/water
Commercial considerations
- Per-bird CAPEX lower than cage-free at commercial scale
- Regulatory risk premium if targeting export markets
- Retrofit path to enriched or cage-free
Procurement considerations
- Confirm welfare compliance at target-market level, not local minimum
- Egg-belt and manure-belt independent commissioning
- Retrofit optionality clause in contract
Common mistakes
- Building conventional cages in markets moving to enriched or cage-free
- Ignoring manure-belt export handling — bottleneck at flock end
- No stand-by power for cage feed lines — welfare risk
- Floor flatness out of tolerance — belt misalignment
Ask suppliers
Ask for target-market welfare-compliance certification and cracked-egg data over a full 60-week production cycle.

Frequently asked
Are cage systems still allowed?
Conventional cages are banned in the EU, UK and several other markets. Enriched cages remain compliant in most of the world. Confirm current status in your target market — cage-free trends continue globally.
Cage or cage-free for a new project?
Depends on target market. Export to premium retailers usually demands cage-free. Domestic markets in Asia, Africa, Latin America and the Middle East often remain cage-based. HatchMatch models both scenarios in the layer investment page.
