Chickens are the most widely domesticated fowl, raised worldwide for their meat and eggs. Male chickens, called cocks or roosters, have been used as fighting animals and for meat production, while female chickens, or hens, are used for egg-laying. In the early 20th century, chicken meat and eggs became mass-production commodities, with modern high-volume poultry farms emerging in Great Britain around 1920 and in the United States after World War II. Chickens raised for meat are often referred to as broilers or meat birds to differentiate them from those primarily used for egg-laying, known as layers. Broilers are selectively bred to grow abnormally fast, resulting in various health issues and a short lifespan, typically slaughtered at just six weeks old.

Meat chickens are bred to grow abnormally fast, causing health problems
Broiler chickens, or chickens raised for meat, have been selectively bred to grow abnormally fast. This is done to maximize productivity and economic benefits, but it comes at a cost to the health and welfare of these chickens.
The chickens' muscles and organs struggle to keep up with their rapid growth, leading to various health issues. Many meat chickens experience chronic pain and lameness due to their underdeveloped legs being unable to support their massive bodies. In severe cases, their legs collapse entirely, leaving them immobile. According to a 2013 study by the Ministry for Primary Industries (MPI), over a third of chickens on factory farms had mobility issues. Lame chickens may suffer from internal bleeding and burns from lying in urine-soaked soil, and they often die of dehydration or starvation as they cannot reach their food and water.
The fast growth of meat chickens also puts pressure on their hearts, resulting in heart disease and death. Their underdeveloped hearts struggle to keep up with their rapid growth, and they may die from a lack of oxygen. Additionally, their large breasts cause muscle tissue to receive insufficient oxygen, leading to muscle fiber breakdown, a condition known as "white striping." This condition, along with "spaghetti meat," where chicken meat resembles noodles, affects the quality of the meat and may reduce its protein content.
To address these welfare concerns, initiatives such as the Better Chicken Commitment aim to improve the health and living conditions of meat chickens. This involves transitioning to healthier chicken breeds that grow at a more natural rate. While consumer awareness of chicken production methods is low, there is a growing preference for higher-welfare animal products, which is driving change in the industry.

They are slaughtered at just six weeks old
Chickens raised specifically for meat are called broiler chickens. They are selectively bred to grow abnormally fast, reaching slaughter weight between four and six weeks of age. This means that they are slaughtered at just six weeks old.
The fast growth rate of broiler chickens causes them to suffer from various health issues. Their muscles and organs struggle to keep up with their rapid growth, leading to lameness and chronic pain. Some chickens even suffer organ failure within weeks of being hatched. This explosive growth puts a lot of pressure on their young bodies, and many have trouble walking due to their underdeveloped legs. In some cases, their legs completely collapse under the weight of their bodies.
The selective breeding of broiler chickens has led to large pectoral muscles, which interfere with natural mating. As a result, artificial insemination is often used in the poultry industry. Additionally, the large amount of breast tissue can make these chickens top-heavy, causing them to fall over and struggle to access food and water.
To address the welfare concerns associated with the intensive breeding of broiler chickens, initiatives like the Better Chicken Commitment have been introduced. This commitment aims to improve the health and living conditions of chickens bred for meat by promoting a change to healthier breeds that grow at a more natural rate. Despite these efforts, the mass production of chicken meat remains a global industry, with a few breeding companies supplying the majority of the world's breeder-broilers.

Heart disease is common due to their underdeveloped organs
Chickens raised for meat are often referred to as "broilers". Over the 7,400-year history of chicken domestication, roosters (male chickens) have been used for fighting, breeding, and meat production. Females (mature hens and younger chickens, called pullets) are raised for meat, eggs, and breeding.
The broiler breeds used commercially for meat grow at an abnormally fast rate, doubling in size each week until they are slaughtered at just six weeks old. This explosive growth puts immense pressure on their young bodies, leading to various health issues and suffering. Their muscles and organs struggle to keep up with their rapid growth, resulting in many health problems.
The fast growth of chickens reared for meat can lead to heart disease due to their underdeveloped organs. Their hearts and other organs cannot keep up with the rapid growth, causing distress and even death. This is exacerbated by the selective breeding practices of the poultry industry, which prioritize large amounts of breast tissue, making the birds top-heavy and prone to falling over. The abnormal growth rates also cause lameness, with over a third of chickens on factory farms struggling to move due to leg abnormalities.
The suffering of these chickens is largely unknown, and their short lives are filled with pain. They are bred to grow unnaturally fast, causing chronic pain, lameness, and organ failure. Many cannot even lift themselves off the floor to reach food or water, and some struggle to breathe. While backyard chickens or pet birds tend to be healthier due to regular exercise and a quality diet, commercially raised meat chickens often suffer from health issues caused by their rapid growth.

The term for a chicken raised for meat is a broiler
Chickens are perhaps the most widely domesticated fowl, raised worldwide for their meat and eggs. The term for a chicken raised for meat is a "broiler". Broilers are chickens that are bred and raised specifically for meat production. They are typically white-feathered and have yellowish skin. Broiler chickens are susceptible to several health issues due to extensive breeding for rapid growth. These issues include skeletal malformations, skin and eye lesions, and heart conditions. The abnormal growth rate of broilers can lead to chronic pain, lameness, and even organ failure in some cases.
Broilers are typically slaughtered between four and six weeks of age, but slower-growing breeds may reach slaughter weight at around 14 weeks. The commercial production of broiler chickens is a highly industrialized process, with mass production being a global industry. In 2004, nearly 47 billion meat chickens were produced worldwide, with the US, China, the EU, and Brazil being the top producers.
The term "broiler" specifically refers to chickens raised for meat to differentiate them from "layers", which are chickens raised for egg production. This distinction is important in the poultry industry to ensure proper management and care for the specific purpose of each group. While both broilers and layers experience health issues due to selective breeding, the focus of their care and living conditions will differ based on their intended use.
It is worth noting that the term "broiler" may also be used to refer to younger chickens under a certain weight, as compared to larger roasters. Additionally, artificial insemination and selective breeding for growth have interfered with natural mating patterns in broilers, as they have developed large pectoral muscles.
The development of modern broiler breeds has evolved over time, with pedigree breeding beginning around 1916 and the first crossbreed being introduced in the 1930s. Today, broiler chickens are a significant source of meat globally, surpassing beef in industrialized countries and gaining popularity in Asia.

Broilers are susceptible to several welfare concerns, including skeletal malformation
Broilers, or chickens raised specifically for meat production, have been selectively bred for rapid growth and efficiency. This selective breeding has resulted in birds with high body weight and a large proportion of breast meat. While this practice has benefits for meat production, it has also led to several welfare concerns for the birds.
One of the main welfare concerns for broilers is skeletal malformation and dysfunction. The rapid growth rate of these birds can lead to metabolic disorders and cardiovascular diseases, such as sudden death syndrome and ascites. The focus on increasing breast muscle affects the way chickens walk and puts additional stress on their hips and legs, leading to leg abnormalities and lameness. In some cases, chickens may struggle to walk or even collapse due to their underdeveloped legs being unable to support their body weight.
The fast growth rate of broilers can also cause skeletal problems in the locomotory system, impairing their ability to move. Studies have found a high frequency of bone deformities, such as tibial dyschondroplasia and tibial curvature, in broiler populations. The growth rate has been negatively associated with proper bone development, and slower-growing birds have been shown to have lower rates of bone abnormalities.
In addition to skeletal issues, broilers are also susceptible to skin and eye lesions, as well as congestive heart conditions. The high stocking densities at which they are typically kept can contribute to the development of footpad dermatitis, hock burn, and breast burn. Poor litter quality, such as wet and contaminated bedding, can further increase the risk of these inflammatory and ulcerative skin conditions.
To address these welfare concerns, there has been a growing interest in alternative production systems that prioritize animal welfare and sustainability, including free-range and organic farming methods. The Better Chicken Commitment, for example, promotes healthier breeds that grow at a more natural rate, aiming to improve the lives of millions of chickens annually. By incorporating multi-trait selection goals into breeding programs and implementing improved management practices, the poultry industry can work towards enhancing the physical, mental, and emotional well-being of broilers.
