鸡肉已从20世纪的昂贵肉品，转变为21世纪全球最受欢迎的蛋白质。这种转变不仅重塑了农业景观，也改变了全球的日常饮食经济。从2006年到2023年，全球鸡肉生产量大幅增长，几乎在所有市场都呈现消费上升的趋势，且这种增长速度近年来仍在不断加快。

鸡肉产业的发展源于冷藏技术、铁路运输和城市需求的推动，并透过品种改良和标准化生产实现了大规模商业化。虽然美国开创了工业化养鸡模式，但如今巴西已成为全球最大的出口国，而亚洲、中东和非洲等地区基于粮食安全与就业考量，也正积极推动在地化的鸡肉生产供应链。

尽管全球对鸡肉的需求远未达到巅峰，但其产业扩张正面临日益严峻的挑战。工业化养殖场带来的环境污染、禽流感疫情的爆发，以及动物福利问题，引发了强烈的社会反弹与法律争议。这些来自社区的抗议与反对，使得新建农场和加工厂变得更加困难，成为限制鸡肉产业未来发展的主要阻力。

Chicken has transformed from an expensive 20th-century meat choice into the world's most popular protein in the 21st century. This shift has reshaped both agricultural landscapes and the global everyday food economy. From 2006 to 2023, global chicken production experienced massive growth, with consumption rising in almost every market, and the pace of this expansion has continued to accelerate in recent years.

The development of the chicken industry was driven by refrigeration, railways, and urban demand, achieving mass commercialization through breeding improvements and standardized production. While the US pioneered the industrial model, Brazil is now the largest exporter, and regions like Asia, the Middle East, and Africa are actively developing localized production supply chains driven by food security and employment goals.

Although global demand for chicken is far from reaching its peak, the industry's expansion is facing increasingly severe challenges. Environmental pollution from industrial farms, avian flu outbreaks, and animal welfare concerns have sparked strong public backlash and legal disputes. Community opposition and protests make building new farms and processing plants much harder, serving as the primary constraint on the future growth of the chicken industry.
