The document summarizes welfare inspection standards for caged and alternative laying hen systems in Ireland. It outlines requirements for facilities, equipment, ventilation, lighting, litter, feeding, watering, and general animal health and welfare. Standards are specified for both conventional cage and enriched cage systems, as well as alternative free-range systems, with a phase-out timeline for conventional cages. Inspection involves checking compliance with these standards to ensure hen health and comfort.
