Manual catching and mechanical harvesting of broiler chickens causes significant acute welfare harm that can be substantially reduced through training, design, and mechanical harvesting systems.
Catching and loading is one of the most welfare-compromising events in the commercial broiler lifecycle. Manual one-leg carry causes pain, joint stress, and disorientation in birds already challenged by fast-growth leg problems. The catching environment in darkened, crowded houses is stressful, and injury rates from rough handling are significant. The welfare of catching staff is also a factor, with training quality directly affecting bird welfare outcomes. Investment in mechanical catching systems and rigorous training standards significantly improves welfare outcomes.
