The Facts about Broiler Chickens
It's easy to pick up those neatly stacked and cleanly cellophaned packs of chicken breast, legs and thighs from the supermarket shelves, never giving a thought as to how it actually got there. We're almost all guilty of this apathy because we're so used the convenient life. Chicken is so versatile. The mainstay of practically every diet sheet and good food guide going. Mouthwatering tempting, going around and around on those roasting spits, it's hard to resist popping one or two in with your shopping for a quick, cheap and easy meal. Meat eating to the majority of us is natural, normal and enjoyable, but do many of us actually know the truth of animal suffering that allows us the never-ending conveyor belt of convenient, fresh meat. Probably not.
Chickens are probably the most abused of all factory-farmed animals. Chicken rearing is the most intensified and automated type of livestock production.
How many chickens are there in the UK?
Around 800 million broiler chickens are reared and slaughtered in the UK each year. The vast majority of these birds are kept in very intensive conditions.
How are the birds kept?
Broiler chickens spend their short lives in huge windowless sheds. The birds do not live in cages but are kept on the floor on a layer of litter. Each shed may contain a carpet of up to 100,000 birds. When chicks are small they have plenty of room to move around. However by the time they are 5-7 weeks of age, space is at a premium. Each bird may have an area smaller than an A4 piece of paper.
Initially lighting is bright to encourage maximum feeding and drinking. However after about three weeks it is usually dimmed to suppress aggression which can lead to fighting and heart attacks. Light may remain on for 23½ hours per day. This is because prolonged inactivity (rest) is economically undesirable as sleeping birds don't eat and drink and put on weight.
Broiler sheds are never cleaned out during the lifetime of one 'crop' of birds so the litter becomes impregnated with the birds' droppings and urine. This combined with inadequate ventilation, water spillage from drinkers, diarrhoea etc can create filthy litter. Forcing the birds to live in these conditions means they can develop painful hock burns, breast blisters and ulcerated feet. High ammonia levels can also cause blindness. Keeping broilers in such poor conditions not only inflicts suffering on the birds but also poses serious threats to human health. Salmonella and campylobacter, the main sources of food poisoning in humans, are commonly found in broiler chickens.
There are 85 veterinary medicines currently authorised in the UK for use in chickens. 37 of these are for therapeutic use and the remaining 48 are for prophylactic use.
These chickens have been specially bred by means of genetic selection over many years to grow quickly and put on weight (meat) quickly. The rapid growth also arises from the use of rich diets and, often, in feed-growth-promoting antibiotics.
What grows quickly is the muscle, which is what is eaten as meat. The legs and bones, however, do not develop at the same pace and often cannot properly support the overgrown body. As a result, each year, tens of millions of broilers suffer from painful, often crippling leg disorders. Around 90% of broilers suffer from walking difficulties and in about ¼ of these it is serious and painful. In the worst cases, birds can't walk at all. Many die from ascites, a condition which means that the birds' heart and lungs are also unable to keep pace with the rapid body growth. This results in millions of chickens dying each year of heart disease before they are even 42 days old.
