Farmed Chickens and the Chicken Industry

There are two types of chicken on British farms: those reared for their flesh and those bred for their eggs. Both endure some of the worst conditions on farms, and they are killed in far greater numbers than any other species, making them the most abused animal in the farming world.

Chickens reared for meat

900 million chickens are slaughtered for meat in the UK each year, and the vast majority – around 94 per cent – are reared inside factory farms.[1] There is nothing natural about their lives. They do not get to scratch in the dirt, dustbathe or even breathe in fresh air. Because they have been bred to grow as big as possible as quickly as possible, their bodies outgrow their bone strength and their legs may break beneath them. Those who cannot stand up suffer skin burns from the ammonia in the litter. Their hearts cannot cope with their ballooning weight either, and heart failure is all too common.

Hens used for eggs

There are three farming systems within the UK for producing eggs: caged, barn and free-range.

Cages

Although the battery cage was banned in the UK in 2012, millions of birds were simply moved into ‘colony cages’ which are bigger, have one small perch and a scratchpad, and a lot more hens inside. There can be as many as 80 birds to a cage. They will never be able to express their natural behaviours, such as nesting, foraging and dustbathing. Artificial lights are switched on for prolonged periods, encouraging them to lay even more eggs.

Many chickens suffer foot deformities from standing on the wire cage floors, while others are completely featherless. The overcrowded conditions allow disease to spread quickly.

More than one-third of all eggs produced in the UK come from hens who are kept in cages. [2]

Barn systems

Around 4 per cent of eggs come from barn-reared hens. The word ‘barn’ may suggest an old-fashioned coop in a farmyard but in fact these huge warehouses can hold up to 16,000 birds. They have more space to move around in but they still do not have access to the outdoors, and the overcrowding creates the same welfare problems for them as for those birds kept in cages.

Free-range

Free-range is not all it’s cracked up to be. Forget a few happy hens running around a yard, this is a large-scale industrial business, with tens of thousands of birds kept inside a barn. Along the sides are ‘pop-holes’ which allow hens access to the outside world, but only when weather permits. Because hens are territorial, weaker birds may not cross a stronger bird’s space, and will never get outside. Those who do venture out may be more susceptible to disease because they are the same in-bred strains as those in closed systems and are not hardy enough to cope with bugs in the outside world.

Suffering in all systems

No matter the system, suffering is inherent in egg-production. The birds’ breeding and environment are manipulated to ensure they lay as many eggs as possible – around 300 per bird per year. All those eggs need shells, and shells are made from calcium. This mineral is taken from the birds’ bones which leaves them susceptible to broken legs and wings. It’s a price the industry is willing to pay for plentiful eggs.

The stress of living in these conditions can cause the birds to wound one another. The industry’s response is not to give them a better life, but to remove the end of their beak when they are day-old chicks. It’s a process that is painful, and complications can cause life-long suffering.

Their lives are short and for male chicks born into hatcheries, very short indeed. They are the wrong sex to lay eggs, and the wrong breed for meat, and so their lives are deemed to be worthless. Millions of them are gassed to death on their first day of life.

Their sisters are useful only while their egg-production is at a peak. When it starts to decline, they are disposed of, too. They are sent to slaughter, and their scrawny bodies turned into low-grade chicken products when they are typically just 18 months old.

All chickens are sent to slaughter

Chickens reared for meat and those used for eggs are all sent to slaughter, and it’s a process that is both painful and frightening for the birds. They may be caught by catching gangs, who grab several birds at a time, holding them by their legs, wings and sometimes necks, and stuff them into crates. This rough treatment often results in hip dislocation and broken bones.

Some farms have mechanised ‘harvesting’, where a machine sweeps the birds onto a transport belt and into a drawer.

Transportation

There is no specific maximum journey time for transporting chickens. Some birds will have to face long-distance journeys in transport lorries, which can last 24 hours for newly-hatched birds and 12 hours for adult birds before they are provided with food and water.[3]

At the slaughterhouse, the birds are shackled upside down by their legs while fully conscious. Imagine the pain of being suspended this way on broken legs. The line moves, dragging the birds’ heads through electrified water which should render them unconscious. But, if the birds are small or the water level is too low or insufficient voltage is used, the chickens will go to the knife fully conscious. Stunned or not, the line keeps moving, and the birds’ necks are cut mechanically.

Increasingly, chickens are stunned and killed by exposure to carbon dioxide gas, a process that, according to Compassion in World Farming ‘causes the birds respiratory distress – hyperventilation and gasping’.[4]

There is no kind way to rear chickens, and no kind way to kill them, either.

Smart, sweet and social

Anyone who has ever met a chicken will know what huge characters they can be. They are active, inquisitive and love to root around, foraging and exploring. They dustbathe and preen to keep their skin and feathers in tip-top shape, and love to sunbathe, lying on their sides, wings outstretched, eyes closed.

As soon as they hatch, they are able to recognise their siblings and, if given the chance, will choose to stay with each other. They are social animals, and form strong friendships, but the huge flock sizes on modern farms are unnatural and stressful.

We use the phrase ‘mother hen’ to describe someone who is a very protective mother, and that’s because chickens are fantastic mums. Even while still in the egg, they will communicate with the embryo, and he or she will respond. The bond is powerful and it begins even before the chick has even hatched.
