Consumer perceptions of egg-laying hen housing systems.

The egg industry has transitioned, or is in the process of transitioning, from conventional cages to alternative hen housing systems in response to legal changes in many states across the United States (US). However, consumers find it is increasingly difficult to understand the details behind those labels and specific attributes conveyed. There are multiple hen housing options with a wide range of costs and impacts on hens, workers, and the environment. This research furthers the understanding of US public perceptions and attitudes related to hen housing systems and corresponding animal welfare, worker, economic, and environmental effects. Results reveal that the US public perceives cage-free aviaries as achieving essentially the same positive impact on hen health and stress, hen behavior, and environmental impact as free-range systems when compared to conventional cage systems. The information provided can assist industry, marketing, and policy decisions with respect to hen housing.
