Mobile Egg Production Units: Welfare in Moveable Poultry Systems

Mobile or moveable poultry houses allow laying hens to access fresh pasture regularly. These systems offer welfare benefits but require careful management to realise their potential.

Key Facts

Mobile units are typically small - 50 to 500 hens - moved to fresh ground every 1 to 4 weeks
Rotating hens to fresh pasture reduces parasite burdens, particularly coccidiosis and nematodes
Mobile systems allow vegetation recovery and reduce poaching of ground compared to static free-range
Hens in mobile units typically show higher range utilisation than static free-range equivalents
Predator protection requires electric fencing moved with the unit, adding management complexity
Mobile systems are labour-intensive and may not scale economically to large commercial operations
Some supermarket welfare tiers now specifically recognise mobile housing as a premium production standard

Welfare Considerations

Mobile production systems address key welfare limitations of conventional free-range: access to genuinely fresh, vegetation-rich pasture with lower parasitic challenge. Hens in mobile systems typically show more natural foraging behaviour, better feather cover, and lower pecking injuries than static free-range peers. The welfare benefits depend heavily on management quality - poorly managed mobile systems can still produce overcrowding, disease and poor hen welfare.

What You Can Do

Seek out eggs specifically from mobile or pasture-raised systems at farmers markets and specialist retailers
Ask supermarkets to introduce mobile-housing eggs as a premium welfare tier
Support the Pasture Promise label which independently certifies true pasture-based egg production
Consider keeping a small backyard flock with rotational grazing as a welfare-positive alternative
