In the past, chickens could live for fifteen to twenty years, enjoying a much longer and natural lifespan. However, due to modern agricultural practices, the average lifespan of broiler chickens has drastically decreased, with many being slaughtered at just six weeks old. This significant reduction in life expectancy highlights the profound changes in poultry farming aimed at maximizing productivity.

The growth rates of these chickens have surged, increasing by approximately 400 percent compared to earlier generations. This rapid growth is a result of selective breeding and industrial farming techniques that prioritize size and weight over the well-being of the animals. These practices not only affect the chickens' quality of life but also raise ethical concerns about the treatment of livestock in contemporary food production systems.
