Green Chicken Poop: Causes and How to Treat

At the sight of green chicken poop, every chicken farmer must be worried. Well, you shouldn’t get worried in some cases.

Diarrhea in chickens and other poultry birds is nothing to take for granted because it is usually a sign that something is not right with the birds. The colour or texture of chicken poops gives a lot of information about the health or general wellbeing of chickens.

This is why it is important for you as a farmer to pay attention to the texture and colour of the faeces of your birds since depending on the colour of the chicken poop will help you diagnose disease.

Diarrhoea in chickens has many causes, and depending on the problem, poop or faeces can appear in difference forms. Therefore, in this article, we will talk about what are the possible causes of green diarrhoea or green poop in chickens and what you should do about it.

Causes of Green Diarrhoea in Chickens

Before I proceed to the causes of green diarrhoea in chickens, I will like to highlight some causes of green poo excluding disease reasons.

  • W a chicken is not eating and drinking well or has no access to feed, it may start to pass out green faeces. This is because the bile secreted to digest feed has no feed to work on and it is passed out together with the faeces.
  • When chickens feed on green vegetables, leaves, seeds or leaves, they are bound to excrete green poo. So if your birds are on free range and you discovered they are passing out green poo, it might be due to the greens they consumed some hours ago.

There are some diseases that cause chickens to excrete green watery poo. If you are engaged in raising chickens and are currently facing this problem, pay attention to the following, as we will mention the most common diseases that cause green diarrhea in chickens.

Newcastle Disease

Newcastle disease is caused by a paramyxovirus and is quite contagious. The most common form of transmission is through faeces or poop from infected birds or sneezing. The main symptoms of chickens with Newcastle disease are as follows:

  • Greenish diarrhea showing lack of feed intake
  • Breathing problems such as coughing and wheezing
  • Hoarseness
  • Trachea rales
  • Birds usually place their heads between the legs or back between the shoulders.

The mortality risk is 50% in young birds. In laying chickens, the egg production declines or even ceases. Although the egg production resumes after six weeks, the eggs laid will have a very thin and deformed shell and in some cases have no shell.

Fowl Cholera

Fowl Cholera is a disease caused by a bacterium called Pasteurella multocida. The disease is also referred to as Pasteurellosis. It is highly contagious and can cause very high mortality in chickens. The most common form of transmission is through the faeces of diseased birds that contaminate water and feed. Birds can also become infected when healthy ones peck at the carcass of another bird affected by fowl cholera.

The main symptoms of fowl cholera include:

  • Green diarrhoea
  • Breathing difficulty
  • Swelling of the wattle and face
  • Loss of appetite
  • Rapid weight loss
  • Low egg production
  • Paralysis due to inflammation of the toes and legs
  • Ruffled feathers
  • The chins can turn red and are warm to the touch

This disease causes the sudden death of birds that appear to be healthy. Due to the speed of the infection it is difficult to treat it in time, with green diarrhea being the earliest symptom of the disease to be able to intervene.

Treatment for Green Diarrhoea

Some of the treatments to be performed in order to fight the above diseases are explained below.

For Fowl Cholera (Pasteurellosis)

If you detect that a chicken is suffering from avian cholera, immediately use sulfaquinoxaline, sulfamethazine or sulfamerazine. You can also use enrofloxacin and fosfomycin to treat the disease. Administer the drugs to the whole flock for five days.

It is imperative to disinfect the pen or house where the birds live in order to prevent reinfection. After disinfecting the pen, you should give the birds a fowl cholera vaccine. The vaccine should be administered every four months.

For Newcastle Disease

At present, Newcastle Disease has no treatment or cure. Therefore, it is best to vaccinate the chickens to prevent the disease. The vaccine should be repeated several times during the life of the animal.

The first vaccination is recommended during the first seven days of the chick with the right strain (depending on location). The next vaccination is performed between four and twelve weeks of life of the chicken. During this period onwards, the chickens should be vaccinated with the La Sota strain every three months.

As highlighted in this article, green diarrhoea in poultry birds is usually a sign that the birds have a health problem that could threaten their lives and performance. Thus, if you observe that your birds are excreting green poop, you should seek the service of a veterinarian to ascertain the cause and arrest the situation as soon as possible.
