The catching and crating of broiler chickens and spent hens before transport is one of the most acute welfare challenges in commercial poultry production, with millions experiencing rough handling daily.
Catching and crating is a period of acute stress for poultry regardless of how well the birds have been kept during rearing. Inverting birds causes fear, muscle fatigue, and cardiovascular stress. Rough handling causes bruising, fractures, and dislocations. Welfare improvements require investment in catcher training, monitoring of handling quality through post-mortem welfare indicators, and consideration of mechanical harvesting where appropriate. Reducing the time between catching and slaughter also reduces cumulative stress.
