  • Over 95% of laying fowls in the UK are now housed in conventional battery cages. In recent years the general public and more specifically an Agricultural Committee on Animal Welfare in Poultry (1981) have raised doubts concerning the welfare of hens maintained this way and have called for further studies on alternative systems.

    Consequently investigations into three alternatives to battery cages have been initiated: a range and covered strawyard system at The West of Scotland Agricultural College and a modified deep litter system at The East of Scotland College of Agriculture. The main objective of these investigations is to determine the practical feasibility and welfare consequences of the respective systems as alternatives to cages for keeping laying fowls. As well as recording productivity, the behavioural activities and distribution of wing-tagged birds have been monitored within the flocks of both the strawyard and deep litter systems. In all three studies ISA Brown layers were used and compared with sister stock housed in cages.
