Recently, there has been increasing focus on the impacts of the rearing environment on long-term behavior, health, and welfare of layers. Enriching the rearing environments with physical, sensory,and stimulatory additions can help to maximize the bird’s developmental potential. This review describes the available literature regarding enrichments provided during rearing and the subsequent impactthey have on different aspects of behavioral and physiological development, including identifying theways enrichments could have biological impact.The behaviour of the birds and their needs (dustbathing, perching, foraging) will improve their well-being and will probably result in a bird that is better able to respond to infections. But what exactly the mechanism behind the positive impact of enriched housing environments is on immunocompetence are currently poorly understood due to limited research in this area. There is a need to identify practical costeffective enrichments that producers would use on-farm and to have commercial validation of positive impacts on aspects of behavior and biology.
