Combination systems are high risk

With many types of systems available on the market, understanding what constitutes a true cage-free system is essential for making future-proof investments, ensuring a smooth market transition, and maximising the welfare of laying hens.

Combination systems (also referred to as “convertible” or “hybrid” systems) are not a suitable alternative to true cage-free systems because they feature doors and partitions throughout each level of the structure. These doors can confine birds in cages, either routinely or permanently when shut. Even when the doors are open, these systems compromise hen welfare due to the high stocking densities and difficulties they pose for the birds trying to move around the system.

Limited access systems are also a concern, with doors located only on the bottom of the structure they limit movement in and out of the system and those doors can also be closed to become caged production. Their design also leads to overcrowding, especially when hens try to access the littered floor simultaneously or move towards perches and nest boxes at the top of the system.

Both limited access and combination systems limit natural behaviours such as dustbathing, scratching and pecking, and can lead to behaviours that exhibit stress and frustration.

To safeguard the authenticity of any cage-free commitments, Compassion asks companies to publish updated language in their cage-free commitment specifying that they will not allow combination or limited access systems in their supply chains.

Companies must do their due diligence to ensure these systems are not used and instead invest in well-designed, spacious aviary systems that meaningfully improve the lives of laying hens.
