Catching and crating of broilers for slaughter transport represents a critical welfare pinch-point, causing injury, fear, and physiological stress. Manual catching involves carrying birds by the legs — a practice causing wing and leg injuries in 1–3% of birds. Mechanical harvesting machines (harvesters) collect birds in darkness with reduced handling stress but can cause wing damage if poorly calibrated. Catching during daylight increases fear and struggle; low-light catching reduces these responses. Crate stocking density and journey duration further determine outcomes. Research shows pre-slaughter mortality rates of 0.1–0.3% are largely preventable through better catching practice, crate design, and journey management. Welfare certification schemes now specify maximum journey times and mandatory dim-light catching protocols.
