The catching and loading of broiler chickens for slaughter is associated with injury and distress that affects hundreds of millions of birds annually.
Manual catching of broilers involves teams of workers grabbing birds by their legs and carrying them inverted to transport crates. Struggling birds suffer dislocated hips, fractured wings, and haemorrhaging from rough handling. Night catching reduces bird activity but does not eliminate injury risk. The scale of catching operations — over 1 billion broilers annually in the UK — means that even small injury rate reductions affect millions of individual welfare outcomes. Mechanical catching and improved crate systems offer welfare improvements.
