This collection features three peer-reviewed literature reviews on feather-pecking in poultry. The first chapter describes the three main forms of injurious pecking (IP) in poultry: tissue pecking (TP), aggressive pecking (AP) and feather-pecking (FP). It discusses the origin of severe FP, the most severe form of IP. The chapter concludes with a discussion on the risk factors and current management strategies used to reduce IP in poultry production. The second chapter assesses the use of beak trimming of laying hens as an effective preventative strategy for injurious pecking (IP). It considers the welfare costs and benefits of the two different methods: hot blade (HB) and infrared (IR). The chapter concludes with a section on alternative strategies that could reduce the need for beak trimming. The final chapter reviews the different types of feather pecking and considers the origins of this behaviour. The chapter offers a detailed discussion on the management techniques available for the prevention of feather-pecking, during both rearing and the laying period.
