The welfare of egg-producing poultry is a topic of great concern to the poultry industry and to researchers in applied animal behavior. It is also subject to increased legislation. Issues such as battery cages, space requirements, access to daylight and "free-range" eggs have attracted public interest. This book brings together edited papers from the 27th Poultry Science Symposium of the World's Poultry Science Association (UK branch), held in Bristol in July 2003. Topics covered include: welfare issues, perception and cognition, behavior, health and diseases, stockmanship and the environment, handling, slaughter and transport, and perspectives of consumers and producers.
