The comb of a chicken is a red (fleshy) area on top of a chicken’s head. It helps to indicate the bird’s health status. A red comb is a sign of a healthy comb but can sometimes develop black spots. These black spots are not a disease themselves but a symptom of underlying health issues.
As chicken keepers, it is our duty to maintain the health of our birds. Observing and investigating black spots can help identify specific health issues. Maintaining overall chicken health, protecting them from contagious diseases, and seeking timely veterinary care are essential steps in preventing and addressing black spots on the comb.
Understanding the reasons behind these black spots can help in managing and ensuring the well-being of your flock. Let’s explore the causes and reasons of black spots on a chicken’s comb.
1. Fowl Cholera
Considered a highly contagious disease, Fowl Cholera is identified by the purple spots on the chicken’s comb. The symptoms include oral discharge, coughing, diarrhea, and swollen joints. Other symptoms might include fever, wattle swelling, and loss of appetite.
Sometimes, it can even lead to the death of the chicken.
Cats and swine carry the bacteria causing Fowl Cholera. While big hens and pullets are at risk, the bacteria can cause harm to chickens of any age. Antibiotics such as tetracycline and penicillin are effective against the disease. Also, vaccination can prevent the disease from happening.
Despite precautions and medications, the bacteria can return. That’s because it can stay in the soil for a long time. Using disinfectants can give good results. But you have to keep your poultry away for a few weeks. The bacteria may return when you introduce new birds.
2. Fowl Pox
It is another viral disease common in birds and chickens as well. Fowl Pox spreads slowly; you can identify it by the black spots on the comb. Fowl Pox has two different variants: dry and wet forms. You will notice small lesions on your chicken’s skin in the dry form, leading to black scabs.
In the wet form of Fowl Pox, you will notice breathing difficulties in your chicken. Moreover, you may find plaques in the chicken’s mouth and upper respiratory tract. Preventing chickens from this virus is challenging.
They become infected through respiratory transfer and skin abrasions. The disease also spreads when chickens ingest scabs from infected ones. Birds and insects, such as mosquitoes, carry the viruses.
The virus’s slow-moving nature means you have to deal with Fowl Pox for a few months. There is no exact treatment for Fowl Pox as of now. To prevent this disease from occurring, vaccination and replacing the chickens out of the flock is the only way.
3. Avian Influenza
It is another contagious viral infection in chickens that devastated the poultry industry in the past. However, Avian Influenza rarely affects backyard chickens. But it is something that you need to be aware of. To identify whether your chickens suffer from this viral infection, look out for the black spots on the comb.
The symptoms of the strong impact of this deadly disease include respiratory problems, dehydration, face swelling, wattles, and black comb. Sometimes, the infected chickens lay shell-less or soft eggs and discharge blood through the nostrils.
If you believe your chicken is suffering from Avian Influenza or notice black spots on the rooster’s comb, call your vet immediately.
4. Liver Problems
Liver issues in chickens can manifest in various ways and may impact the color and condition of the comb. Liver dysfunction can affect the bird’s overall health and result in changes to the comb, including discoloration or blackening.
Symptoms may include reduced appetite, weight loss, lethargy, and abnormal behaviors. Diagnostic tests, such as blood work and imaging, may be necessary to evaluate liver function accurately.
5. Heart Disease
Heart problems can also contribute to black spots on a chicken’s comb. Cardiovascular conditions may affect blood circulation, leading to poor oxygenation and subsequent changes in comb color. In addition to black spots, chickens with heart disease may exhibit signs such as weakness, difficulty breathing, exercise intolerance, and fluid accumulation in the body.
Veterinary examination, including listening to the heart and diagnostic tests like radiographs or ultrasound, can help assess the heart’s condition.
6. Poor Health Condition
The right way to make sure your chickens are in good health is to watch out for the color of their comb. The comb will discolor and shrivel if a chicken is in poor health. This situation arises because of poor blood circulation due to certain reasons.
The comb fails to display a vibrant rose or red color. There might be legitimate reasons why the comb becomes black. So, it is wise to check out your chickens with a specialist in the poultry industry. I know several cases where chickens were either suffering from liver or heart problems.
When the liver gets damaged, the chicken’s body shuts down. Moreover, if the chicken has heart disease, the first symptom is black spots on the comb. So, consult with a vet whenever you notice a black comb as soon as possible.
7. Frostbite
If you notice your chicken’s comb turning black or purplish, it means it has suffered severe frostbite. Frostbite occurs when the fluid inside the cells of the comb freezes, affecting the tips most.
You need to protect your flock and care for them until they are fully healthy. However, it can be challenging to assess the condition of individual birds. To ensure their well-being, it is best to seek medical advice from an experienced vet.

People assume that their chicken might be suffering from a certain disease when they observe black spots on the comb. Black spots aren’t a disease in chickens. Rather, it is a symptom that your chicken is suffering from severe health issues.
So, whenever you notice a black comb, visit a good vet for better treatment. Keep in mind that any kind of disease in chickens is curable if you take preventive measures at the right time.
