This is the VOA Special English Agriculture Report.


Raising chickens or other birds for the eggs and meat they produce is a popular family
and business activity almost everywhere in the world. The birds eat grain, seeds and
grasses. They also eat small pieces of food that people throw away. Many of these
materials would be wasted if the birds did not eat them. Chicken eggs and meat contain
high quality protein and other substances important in the human diet.


For many centuries, chickens were allowed to run free to find food by themselves. Then
people used fences to keep small groups of birds known as flocks 2 from running away.
After the chickens were kept inside a fence, people had to provide food for them.


Early in the last century, raising flocks of thousands of birds became a successful
business for many people. But the size of these flocks caused some serious problems, including pollution caused
by chicken waste.


Disease 3 is one of the biggest problems in large flocks. The birds are kept close together all the time. So if one
bird becomes sick, the sickness spreads. All the chickens in a flock 1 can die from a serious disease. Diseases 4 that
affect chickens are different in different areas of the world. So medicines that have been successful in treating
chickens in local areas should be used


People who raise chickens should try to prevent disease. Experts advise these steps: Feed the birds a balanced
diet. This will help them resist infections. Do not add adult birds to your flocks. If you must add adult birds, keep
them separate from the flock for five to fifteen days to make sure they are healthy.


Cover the floor of the buildings where the chickens are kept with material like straw, rice husks or sawdust.
Change this material often.


After you sell the chickens, completely empty the building where they were kept. Clean and wash the building.
Then leave it empty for four weeks before putting in new chickens.


Diseases affecting birds are not simple to understand and treat, so expert medical advice is important. You can
get more information about caring for chickens and other birds from the organization Volunteers in Technical
Assistance 5. Computer users 6 can reach VITA through the Internet at w-w-w dot v-i-t-a dot o-r-g. www.vita.org.
