kooivrije

Kooivrije is the Dutch term for eggs produced from laying hens kept in non-cage systems. The descriptor signals that the hens are not kept in conventional battery cages, and it is used as a marketing and informational label in the Dutch egg market. Kooivrije eggs can come from different types of housing, most commonly barns (staldeieren) where birds live indoors with enrichment, or free-range systems where hens have outdoor access.

In practice, kooivrije encompasses a range of welfare-focused production methods. Barn eggs keep hens inside but provide features such as perches, nesting boxes, and litter to encourage natural behavior. Free-range kooivrije eggs add access to an outdoor area, although the proportion of birds outdoors and the conditions of the outdoor space vary by farm and certification. The term became more prominent after the European Union banned conventional battery cages for laying hens, moving producers toward either enriched cages or non-cage, cage-free systems.

The use of kooivrije as a label varies in its specificity. Because it is a broad descriptor rather than a single standardized standard, the precise welfare level depends on the producer and any accompanying certifications. In the Netherlands, kooivrije eggs are often found alongside other welfare labels, such as the Beter Leven certification from the Dutch animal welfare organization, which assigns welfare levels using a star rating.

For consumers, kooivrije indicates a preference for eggs produced without traditional cages, offering an alternative to cage-based production. To gauge exact welfare practices, buyers may look for additional certifications or inquire about farm-specific practices and standards.
