40 days: The Life of a British chicken and the law

For millions of chickens raised in England each year, life is measured not in seasons, but in days, typically 40 days from hatch to slaughter. During that short life, a chicken will pass through multiple legal regimes: welfare at the hatchery, welfare on the farm, welfare during handling and transport, and welfare at slaughter. On paper, this looks like a comprehensive protective framework. In reality, the law fragments responsibility across time and institutions, creating gaps in which suffering is normalised, and, increasingly, legally permitted.

Day zero to end of life

A chicken’s life begins in an industrial hatchery. From the moment they hatch, they are legally recognised as a “protected animal” under the Animal Welfare Act 2006. That Act establishes the foundational duty of care: it is an offence to cause an animal unnecessary suffering and those responsible for animals must meet their welfare needs, including the need to be protected from pain, suffering, injury and disease.

Days 1–39: Life on the farm

Once placed on a farm, the dominant legal regime becomes the Welfare of Farmed Animals (England) Regulations 2007, which implement retained EU law. These regulations require animals to be kept in conditions that do not adversely affect their health or welfare and explicitly prohibit keeping animals whose genotype or phenotype results in welfare harm.

This is the legal framework that governs stocking density, lighting, litter quality and ventilation in broiler sheds. It is also the framework that has been tested in litigation, most notably in R (Humane League UK) v Secretary of State for Environment, Food and Rural Affairs, where the courts examined whether fast-growing broiler breeds can lawfully be kept given their well-documented propensity for pain, lameness and organ failure.

The significance of that case lies not in dramatic reform, but in what it reveals: the law already contains tools capable of addressing systemic welfare problems, yet enforcement is minimal, inspections are rare, and compliance is often assessed against industry norms rather than animal outcomes.

Day 40: Catching and handling

The legal landscape shifts abruptly when the chicken reaches slaughter weight. At this point, responsibility moves from farm management to catching teams and transport operators, and a new body of law applies.

Standard practice on UK farms involves teams of people entering a farm during the night and entering chicken sheds. The catches swoop down to catch several chickens in one hand, often by one leg. They are then carried over to the crates where they are stuffed into, before being loaded onto a lorry. The practice of carrying chickens by their legs, rather than upright results in a number of significant welfare issues. This includes physical injuries like broken bones, dislocations, and bruising. It can also result in suffocation, as inversion impacts chickens’ ability to breathe because they lack a diaphragm to keep their organs away from their lungs. 

Historically, the Welfare of Animals (Transport) (England) Order 2006, implementing retained EU Regulation 1/2005, prohibited the lifting or carrying of animals by their legs and in a way that causes unnecessary suffering. 

For years, however, this prohibition sat uneasily alongside government-issued Codes of Practice for both egg-laying hens and chickens bred for meat that permitted leg-catching. When this contradiction was challenged, the government faced a choice: enforce the law as written, or change it. It chose the latter.

Through a recent Statutory Instrument amending the transport regulations, chickens and turkeys were explicitly exempted from the prohibition on being carried by the legs. In legal terms, this is significant. Rather than welfare law constraining practice, practice has rewritten the law. The most stressful moment in a chicken’s life, when they are collected for slaughter, is now governed by a diluted legal standard, where they will most likely to suffer acute physical injury, broken bones, dislocations, crushing and fear.

Once crated, the chicken falls fully within transport law. The same transport regulations nominally require that animals be fit for transport and protected from injury and distress. Yet fitness is assessed rapidly, the law exists, but the time window for meaningful intervention is vanishingly small.

Day 40: Slaughter

At the slaughterhouse, responsibility shifts again. The applicable regime is the Welfare of Animals at the Time of Killing Regulations 2015, which require animals to be spared avoidable pain, suffering and distress, and mandate stunning before killing (subject to exemptions). 

A life divided by law

The chicken’s life is short, but the law governing it is sprawling, fragmented and inconsistent.

The recent dilution of handling protections is not an anomaly; it is a warning. It shows how easily welfare standards can be adjusted downward when they clash with commercial convenience. If the law is to mean anything for the billions of animals reared in the UK, it must provide meaningful protection throughout every stage of their lives.
