In the context of poultry farming, the term "California cage" refers to a specific configuration within the cage system used to house laying hens.

These cages are typically constructed from wire mesh and are arranged in a distinctive stairstep alignment, which allows for efficient use of space and easier management of the flock. In this setup, birds are confined in individual units, with feed and water troughs attached to the front of each cage. The floors of the cages are designed with a slope, allowing eggs to roll forward into a collection area for easy retrieval. This system is often housed within a laying house, which provides the necessary environment for maintaining the health and productivity of the birds.1
