The catching and crating of broiler chickens before transport to slaughter is a high-welfare-risk procedure affecting billions of birds annually.
Poultry catching is a high-intensity welfare event during which billions of birds experience fear, pain and physical injury annually. Birds are caught by one or two legs, inverted, and placed in transport modules — all highly aversive procedures for chickens. Training catchers in correct technique (four-birds-per-hand maximum, avoiding inversion where possible) significantly reduces injury rates. Mechanical catchers, used by larger operations, reduce contact time and injury rate but can cause bruising if incorrectly set.
