The process of catching, crating, and loading poultry for transport to slaughter is associated with high injury rates and significant stress.
Catching typically occurs at night in darkened sheds. Birds are grabbed by their legs and carried inverted, causing dislocation and fractures. Fear responses elevate stress hormones. Mechanical harvesters collect birds gently but require significant capital investment. The journey to slaughter adds hours of further stress. Injuries sustained during catching cause pain that persists through transport and into the slaughter plant.
