Natural variation in beak shape influences feather pecking

Different birds have different beak shapes. Understanding the natural variation in beak shape could help reduce feather pecking damage in laying hens. Research shows that there is potential for genetic selection of blunter or shorter beaks that do less harm when pecking occurs. Outbreaks of severe feather pecking in laying hen flocks remain a significant challenge for the poultry industry. Research into why hens feather peck and how the behaviour and its consequences can be prevented has been
