“Today’s chickens are true Frankenbirds – genetically modified to grow too fat too fast.”

“We’ve successfully bred most of the chicken out of the chicken.”
-Poultry Farmer

Intensive Confinement


The vast majority of chicken meat found in stores and restaurants comes from birds crowded by the thousands in dark sheds. In the US, more than 8 billion chickens spend their entire short lives on these factory farms, often suffering from respiratory ailments, crippling leg deformities, and even abuse before being trucked to slaughter.

In these cramped, windowless sheds, it is impossible for birds to engage in most natural behaviors, like perching or taking dust baths. Living in their own waste, birds in the chicken industry also suffer from respiratory ailments, ammonia burns, and eye irritations.


Rapid Growth


In the 1950s, it took 84 days to raise a five-pound chicken. Today, because of selective breeding and growth-promoting drugs, birds reach slaughter weight in just 45 days. If humans grew at the same rate as a factory-farmed chicken, we’d weigh 660 pounds by the time we turned two months old.

In today’s chicken industry, broiler birds — a term for birds raised for meat — are killed when they still peep like chicks, yet they have already reached morbid obesity. Such fast-paced growth causes these animals to suffer from chronic health problems, including leg disorders and heart disease. Studies suggest that nearly a third of factory-farmed chickens have such severe leg deformities that they actually have trouble walking.

“If you want to marvel at how humans can mess with nature, look no further than the modern chicken.”


In the days leading up to slaughter, workers gather the bodies of dead birds and break lame birds’ necks, while the living sit in their own waste, often too weak to walk. John Webster, professor emeritus of animal husbandry at the University of Bristol, says that if the birds weren’t killed around six weeks of age, “They wouldn’t survive another two weeks.”

Painful Slaughter


There are no federal laws whatsoever protecting chickens used for food, from the moment they hatch until their slaughter. In this industry, animal welfare has taken a backseat to profits.

Birds are packed up and shipped out to slaughter without food, water, or shelter from extreme weather. At the slaughterhouse, they’re dumped onto conveyor belts and shackled upside down by their legs. Nearly all birds are conscious when their throats are cut. With as many as 8,400 birds slaughtered per hour in a single plant, mistakes are common, and many are still conscious as they’re dropped into tanks of scalding water.

One industry journal asks, “Is it more profitable to grow the biggest bird and have increased mortality due to heart attacks, ascites, and leg problems, or should birds be grown slower so that birds are smaller, but have fewer heart, lung and skeletal problems? … Simple calculations suggest that it is better to get the weight and ignore the mortality.”

Nutritional Quality


These genetically-manipulated animals routinely suffer from muscle disorders like white striping and wooden breast, which seriously decrease the nutritional value of their meat. Degenerative muscle disorders not only cause factory-farmed broiler birds to suffer chronic pain, but also result in an estimated $200 million in economic losses each year.


“The broiler industry has focused on boosting productivity through selection for fast-growth and other intensive production practices. These practices, however, have resulted in poor welfare for broilers, and a lower quality product for consumers; one that does not meet the expectations of a leaner, healthier protein.”



Generating billions of dollars in profit by churning out billions of pounds of chicken meat has always been the chicken industry’s top priority. But today’s consumers are demanding changes in the way animals raised and killed for food are treated, and the industry and food retailers are starting to take heed.

Day-to-Day Abuse


In 2014, a Compassion Over Killing investigation of a North Carolina factory farm supplying Pilgrim’s Corp., the world’s second-largest chicken producer, revealed shocking day-to-day horrors, including birds crippled by painful leg deformities, sick or injured birds thrown around, and live birds dumped like trash into outdoor pits and left to die.

Inside Breeder Barns


In 2016, COK again exposed the chicken industry – this time with a never-before-seen look behind the closed doors of broiler breeder factory farms, filmed inside several Tyson Foods facilities. Footage exposed workers kicking and punching live birds, birds crushed to death by transport crates and run over by forklifts, and workers slamming birds into transport crates.

Because breeder birds must survive to sexual maturity – weeks longer than their rapidly growing bodies have been bred to endure–producers resort to restricting feed or even starving these birds. After COK’s investigation exposed the cruel practice of “boning“, in which a dull plastic rod is stabbed through the nostrils of young male breeder birds to restrict food intake, Tyson immediately announced an end to the practice. Urged by COK, two more top poultry producers quickly followed suit: Perdue Farms and Wayne Farms.
