This report describes the methods of water provision in the current housing and management of broilers and broiler breeders and the possible impact of these management practices on animal welfare (including animal health). It provides an overview of drinking behavior of chickens, the physiology of water intake and factors affecting water consumption in broilers and broiler breeders. Based on scientific literature and expert opinion it is estimated that the current methods of water provision to broiler chickens do not have an effect on welfare. The current methods of water provision to broiler breeders are estimated to affect broiler breeder welfare, but evidence from scientific literature is lacking. It is described which management methods can be applied to reduce the welfare impact of water provision to broilers and broiler breeders. Finally, recommendations for further research are provide
