The transport of poultry to slaughter is a major welfare event affecting billions of birds annually, with temperature extremes, duration, and handling all contributing to significant suffering.
Poultry transport exposes birds to a cascade of welfare insults from catching through to slaughter. Already compromised by fast growth and potential litter injuries, broiler chickens face the additional stresses of handling, confinement in crates, temperature extremes, noise, and movement during transport. The duration of transport means birds spend extended periods unable to access water during what may be the most stressful period of their lives. Heat stress is a particular concern - even moderate temperature increases inside transport vehicles can cause birds to die from hyperthermia. Dead-on-arrival statistics are a measurable welfare outcome that could drive improvements if reporting were mandatory and penalties meaningful.
