About This Book

Free-range laying hen production systems involve providing flocks of hens with the chance to use minimally controlled outdoor areas, rather than keeping them in intensive, environmentally controlled, indoor housing. Such systems are considered more natural and ethical. However, highly productive modern genotypes, selected for cage production, are harder to manage in large flocks and outdoor environments. To sustainably improve free-range housing and management, we must understand how hens behave in these systems, the welfare challenges they face and what modifications will, in practice, adequately address hens' needs. This chapter reviews the following areas of significance and concern: individual differences in range use, behavioural expression on the range, correlations between ranging and health variables, parasite loads, adequate nutrition, grass impaction, feather pecking and cannibalism.
