Ear infections in chickens are often referred to as ear canker and are caused by various bacteria, including E. coli. They can also be caused by ear mites, which can be treated with a few drops of vegetable oil in the ear to smother them. Fungal infections can be treated with antifungal cream. Bacterial infections can be treated with antibiotics, although some bacteria are highly resistant to antibiotics. Inner ear infections are likely caused by a viral infection and are much harder to treat. Symptoms of an ear infection in chickens include ataxia (loss of balance, stumbling, and incoordination), reduced crowing (in roosters), discharge, torticollis (wry neck), head tilt, frequent scratching or rubbing of the head, inflammation around the ear opening, and excessive yawning.

Chickens have ears that are covered by a small patch of feathers. Ear infections in chickens can affect any or all portions of the ear. Inner ear infections (otitis interna) are likely caused by a viral infection and are difficult to treat. Middle ear infections (otitis media) are usually caused by a chronic bacterial infection or tumour.
- Head tilt: A chicken with an ear infection may tilt its head to the side, sometimes also turning its neck over.
- Loss of balance: Also known as ataxia, this is a common symptom of an inner ear infection, which affects the chicken's nervous system.
- Reduced crowing: Roosters with an ear infection may crow less.
- Ear discharge: This often presents as crusty material matted to the feathers covering the chicken's ear opening.
- Inflammation around the ear opening: This can include redness and swelling.
- Excessive yawning
- Frequent scratching or rubbing of the head: The chicken may also shake its head.

Veterinary advice: When to seek professional help and treatment
Chickens have ears that are covered by a small patch of feathers. Ear infections can affect any or all portions of the ear. Inner ear infections (otitis interna) are likely caused by a viral infection and are difficult to treat. They can cause neurological symptoms such as head tilt, loss of coordination and balance, and torticollis (wry neck). Middle ear infections (otitis media) are usually caused by chronic bacterial infections or tumours. Bacteria can enter through the infundibular cleft, a small opening in the roof of the mouth, and are often resistant to antibiotics.
It is important to seek veterinary advice before applying any treatment or vaccine. A veterinarian can provide guidance on appropriate antibiotics or medications for bacterial infections. They can also advise on the use of vitamins and minerals, such as Vitamin E/Selenium, which may be required to treat wry neck.
If you suspect your chicken has an ear infection, look out for symptoms such as ataxia (loss of balance), reduced crowing, ear discharge, head tilt, scratching or rubbing of the head, inflammation around the ear, and excessive yawning. In some cases, chickens with ear infections may also exhibit lethargy and a closed eye on the affected side.
If you notice any of these symptoms, it is important to consult a veterinarian, especially if your chicken is experiencing difficulty eating or drinking due to the infection. Failure to properly recognise and treat ear infections can be fatal.

Cleaning: Using peroxide, apple cider vinegar, and other products to clean the ear
Ear infections in chickens can be caused by various factors, including bacteria, viruses, and ear mites. While some infections may require veterinary attention and medication, mild cases can be treated at home with natural remedies and over-the-counter products. Here are some cleaning methods to treat a chicken's ear infection:
Using Peroxide
Peroxide is a common disinfectant that can be used to clean a chicken's ear and remove any discharge or buildup. In one instance, a user reported successfully treating their rooster's ear infection by cleaning the affected area with peroxide and then draining the liquid. This process was repeated for several days until the infection cleared. It is important to exercise caution and not to insert any objects too far into the chicken's ear during cleaning.
Apple Cider Vinegar
Apple cider vinegar (ACV) is another natural disinfectant that can be used to treat ear infections in chickens. One user recommended mixing one tablespoon of ACV per gallon of water and administering it to the affected chicken. However, it is important to consult a veterinarian for specific instructions and dosages.
Vegetable Oil
Vegetable oil can be used to smother ear mites, which are a common cause of ear infections in chickens. Using an eyedropper, place a few drops of vegetable oil directly into the chicken's ear canal. This will help to suffocate the mites and improve the infection.
Over-the-Counter Products
In some cases, over-the-counter products can be used to treat ear infections in chickens. For example, fungal infections can often be resolved using antifungal cream. The cream should be gently inserted into the ear canal and applied generously. Additionally, mineral oil can be used to soften any accumulated material in the ear, making it easier to remove.
While these cleaning methods can help treat mild ear infections in chickens, it is always recommended to consult a veterinarian, especially for more severe or persistent cases. They can provide specific instructions, dosages, and medications tailored to the individual chicken's needs.

Medication: Antibiotics, vitamins, and other medications to treat the infection
Ear infections in chickens are often referred to as "ear canker", and they can be caused by various types of bacteria, including E. coli and Pseudomonas aeuroginosa. These bacteria are opportunistic pathogens that take advantage of birds with compromised immune systems and are often spread through contaminated feed, water, and droppings.
To treat a bacterial ear infection in chickens, appropriate antibiotics should be used. For example, the antibiotic polymyxin B is highly effective against Pseudomonas aeuroginosa. Other medications that may help are gentamycin, amoxicillin, and fluoroquinolone. It is important to note that not all bacteria strains are resistant to antibiotics, so the choice of medication depends on antibiotic sensitivity testing.
In some cases, inner ear infections in chickens may be caused by a viral infection, which can be much more difficult to treat. If your chicken is experiencing neurological symptoms such as head tilt, loss of coordination, and wry neck, it is important to seek veterinary advice as they can guide you on the best course of treatment for viral infections.
Additionally, vitamins and supplements can play a crucial role in supporting the overall health of your chicken, especially if it is struggling to eat or drink due to the infection. For example, Vitamin E and Selenium supplements can be beneficial, and these are available in injectable form from your veterinarian.
It is always recommended to consult with a veterinarian, especially one specialized in poultry care, before administering any medication to your chicken. They can provide specific advice and guidance based on your chicken's individual needs and the type of ear infection it is experiencing.

Prevention: Preventing ear infections through hygiene and flock management
Ear infections in chickens are often referred to as "ear canker". Canker is caused by various bacteria, including E. coli, and Pseudomonas aeuroginosa, which is a gram-negative flagellate bacterium. Bacteria causing ear infections are opportunistic pathogens that take advantage of birds with compromised immune systems. They are often prevalent in the environment and spread through contaminated feed, water, droppings, and bird-to-bird contact.
To prevent ear infections in your flock, it is important to maintain high standards of hygiene and flock management. This includes regularly cleaning and disinfecting coops and enclosures to reduce the presence of bacteria. Ensure that your chickens always have access to clean food and water, and that their food and water sources are not contaminated. It is also important to prevent chickens from consuming the carcasses of infected birds, as diseases such as Trichomonas gallinae can be spread in this manner.
In addition to hygiene practices, flock management can help to prevent ear infections. This includes regularly monitoring your chickens for any signs of illness or infection, such as head-tilting, loss of balance, reduced crowing, ear discharge, and scratching or rubbing of the head. If any of these symptoms are observed, separate the affected chicken from the rest of the flock to prevent the potential spread of infection. It is also important to treat chickens for mites and fungal infections, as these can contribute to ear infections.
Active prevention is critical to ensuring your chickens avoid the chance of infection. By maintaining high standards of hygiene and proactive flock management, you can help to keep your chickens healthy and happy.

Frequently asked questions
Clinical signs that your chicken has an ear infection include: ataxia (loss of balance, stumbles often, incoordination), reduced crowing (in roosters), ear discharge (often presents as crusty material matted to feathers covering the ear opening), torticollis (aka wry neck), head tilt, frequent scratching or rubbing of the head, inflammation around the ear opening (redness, swelling) and excessive yawning.
You should seek veterinary advice from your local veterinarian before applying any treatment. However, ear infections in chickens can be mitigated through the use of antibiotics appropriate for the bacterial organism that is present. Many medications that are active against this organism have been removed from the marketplace. Today, the standard medication for treating this is metronidazole.
The main reason why chickens die from ear infections is because the infection causes wry neck, which means they are unable to eat and drink. In order to treat a chicken with wry neck, you need to keep her separate from the other chickens and help her eat and drink. She will need extra vitamins and minerals (Vitamin E/Selenium).
