The final hours of a chicken life involve transport stress, handling, and slaughter, where welfare standards vary dramatically between facilities and countries.
Slaughter is the point at which the largest aggregate welfare harm in animal agriculture occurs, yet it receives proportionally less public attention than farming conditions. The scale is difficult to comprehend: billions of individual fear and pain experiences compressed into the final hours and minutes of animals who have already endured constrained lives. The welfare gap between best practice and common practice is substantial. Controlled atmosphere stunning with appropriate gas mixtures can eliminate conscious shackling and provide a more reliable welfare outcome, but adoption has been slow due to capital costs. Meanwhile, water bath stunning remains widely used despite documented inconsistencies in effectiveness. Regulatory standards set minimum expectations but audit compliance is uneven, and the speed of commercial slaughter lines creates persistent pressure that undermines careful welfare practice.
