Perch and nest
Unlike free-range farming, the birds do not have access to the outdoors. The marketing term ‘cage-free’ is often used to describe barn farming.
Currently, 14% of the national layer flock are housed in barn operations. Internationally, barn farming is particularly popular in Northern Europe.
The Animal Welfare (Layer Hens) Code of Welfare 2012 sets out the standards of care and management for layer hens in New Zealand. It includes specific standards for barn egg farming.
