Heng-wei Cheng and Sha Jiang, Livestock Behavior Research Unit, USDA-ARS, USA and Southwest University, China

Chapter synopsis: This chapter reviews current research on the genetics of behavioral traits in poultry, particularly layers. The focus is particularly on aggressive behaviors such as feather pecking which remain a serious problem in both cage and alternative non-cage systems. The chapter shows the complex interactions between genetics and environment, individuals and groups, and how a multi-level group selection approach can be used to reduce aggressive behavior in chickens.
