legkippen

Legkippen are chickens kept primarily for the production of eggs. They are usually female birds, selected and bred for high egg-laying rates, while male chicks are typically culled or used for meat in mixed operations. In standard commercial systems, a laying flock may reach peak production during the first year or two and then be replaced or rehomed.

Housing and production systems vary by country. Conventional battery cages have been banned in the European Union since 2012 and replaced by enriched cages; many producers now use barn or free-range systems, and organic farms may emphasize outdoor access. Welfare considerations, such as space, enrichment, and beak trimming, influence system choice and labeling.

Management focuses on nutrition, lighting, and welfare. Laying hens require a diet high in energy and calcium for eggshell formation, with access to clean water and perches, nests, and litter for foraging behaviour. Lighting is managed to regulate laying cycles, often around 14 to 16 hours of light per day.

Egg production characteristics vary by breed and age. A commercial layer typically begins laying at about 18 to 20 weeks, reaches a production peak in the first year, and may produce around 250 to 320 eggs annually. Production declines with age and hens are commonly culled after one to two years or relocated to non-laying roles.

Economically, legkippen are a major source of eggs worldwide. Welfare, sustainability, and consumer demand drive reforms in housing, antibiotic use, and farm management. Ongoing improvements include better enrichment, breed selection for health and longevity, and more transparent labeling of production systems.
