Chicken Diseases and Treatment

The most common poultry diseases are;

chicken diseases and treatment1. Newcastle Disease

This is one of the big ones! It has absolutely no cure, and the only way to protect your flock is through vaccination. Not once! Three or four times according to the vaccination schedule. Newcastle disease is a serious respiratory disease in chickens. It also affects the digestive and nervous systems. This explains greenish diarrhea and the paralysis once a chicken is in the later stages of the infection. Chicken infected with Newcastle disease are doomed to death because the disease it is a severe disease.

Early Symptoms of Newcastle disease in chickens.

  • Coughing
  • Sneezing
  • HEAVY breathing
  • Green watery diarrhea

Later stages include

  • Twisted neck
  • Paralysis of wings and limbs
  • Stiff bones

Treatment of Newcastle Disease.

The only way to treat Newcastle disease is through vaccination. The vaccine can be administered in two ways; through drinking water and through an eye drop. The most effective method is the eye drop for younger-aged chicken.

2. Infectious coryza

This is a common poultry disease that is very infectious. Infectious coryza can be easily treated in adult birds but it is less common in adult birds. This disease affects the sinuses of the chicken which may cause discharge from the nose and eyes and swelling of the facial areas of the chicken. Sometimes, they can even have swollen eyes that are completely shut.

Common symptoms of infectious coryza are;

  • Mucusy discharge from the eyes, nose, and mouth.
  • Swelling of the facial area and even sometimes completely blinding the chicken.
  • Loss of appetite of the bird leads to loss of weight.
  • Having a problem breathing.
  • Severe diarrhea.

Treatment: Infectious coryza is best treated by using the appropriate antibiotics. Proper care should be taken off the already sick birds to provide a barrier to transmission of the disease to other healthy chickens in the flock.


3. Chronic Respiratory Disease;

This chicken disease is a little bit similar to infectious coryza. A common symptom of crd in chickens is cough. So, this typically may be the reason why there is a cough in your chicken coop accompanied by a sneeze or wheeze. Sounds a little bit weird… These symptoms are caused by a bacteria known as Mycoplasma Galliseptieum. This disease is highly infectious and failure to isolate sick infected birds will cause the disease to timely spread. In my own experience, once this disease affects one of your chickens in your flock, it is important to isolate and treat the infection as quickly as possible. Failure to do so will cause the chicken to be susceptible to another respiratory disease.

Common symptoms of crd in chickens are;

  • Coughing is the most common symptom.
  • Wheezing
  • Consistent sneezing
  • A decrease in appetite leads to a loss in weight.
  • A decrease in growth rate is seen when one of the chicks or chicken in your flock is sizeable smaller than the rest of the same age.


Treatment of crd in chickens.

Treatment of crd in chickens is most commonly done through antibiotics. While treating chickens infected with crd, it is best to isolate them to properly eradicate the disease. Recovering birds should also be well taken care of and not reintroduced into a healthy flock because mild symptoms can be difficult to detect and a recovering chicken is still a potential carrier of the infectious disease.


Which chicken disease is most dangerous?

Rooster, Chicken, Village, Yard, FamilyAlthough there are some poultry diseases with greater severity to a chicken or flock, the degree of attention to the treatment of all infectious diseases should be the same. Infectious diseases are the most dangerous because an added form of isolation is required to protect healthy birds from infection. In my own words, Newcastle disease is the most dangerous because of its effect on a flock of unvaccinated chickens within a short period of time.


How chicken illnesses are spread.

  1. Direct contact with infected chicken manure.
  2. Through people who act as carriers.
  3. Natural elements. i.e wind.
  4. Animals and birds.

What to do to curb the spread of chicken diseases

  1. Isolation.

  3. Use of antibiotics and vaccination if need be.
