Bird hock is a condition that affects the joints and feet of birds, particularly large pet birds like parrots. It is characterized by inflammation, swelling, and crusting of the skin around the joints. Bird hock can be quite painful and debilitating for affected birds if left untreated.
What causes bird hock?
There are a few potential causes of bird hock:
- Perching – Birds that spend a lot of time perching on narrow or abrasive perches can develop sores and irritation on their feet and joints from the constant pressure and rubbing.
- Obesity – Carrying around excess body weight puts increased stress on a bird’s joints and feet, making them more prone to strain and inflammation.
- Arthritis – Degenerative joint diseases like arthritis can cause inflammation and pain in the joints.
- Injury – Physical trauma to the feet or joints, like getting caught in a toy or cage decoration, can result in wounds that trigger hock issues.
- Nutritional deficiencies – Diets low in certain vitamins, minerals, or amino acids may make birds more susceptible to hock problems.
- Unsanitary conditions – Constant contact with wet, dirty cage floors can lead to irritated, cracked skin.
- Bacterial or fungal infections – Infections can attack the skin and joints, causing swelling, crusting, and pain.
What are the symptoms of bird hock?
There are a few signs that may indicate a bird is developing hock issues:
- Swollen, reddened joints
- Crusty or scaly skin around joints
- Calluses or blisters on feet
- Loss of grip strength
- Lameness or favoring one foot
- Reluctance to perch or grip
- Crying out in pain when feet are touched
How is bird hock diagnosed?
Bird hock is usually diagnosed through a combination of:
- Physical exam – Looking for swelling, crusting, calluses etc. Manipulating joints to check for pain.
- Medical history – Asking about potential contributing factors like perches, obesity, arthritis.
- Diagnostic testing – Bloodwork to check for infections or vitamin deficiencies. X-rays or biopsy to assess joints.
How is bird hock treated?
Treatment focuses on both resolving current hock issues and preventing their recurrence. Approaches may include:
- Topical medications – Antibiotic, antifungal, or steroid creams to reduce swelling, irritation, and infection.
- Oral medications – Antibiotics, anti-inflammatories, or pain relievers.
- Improved husbandry – Providing roomy cages, padded perches, cleanliness.
- Dietary changes – Ensuring a balanced, nutritious diet.
- Physical therapy – Stretching and exercising joints and feet.
- Weight management – Helping obese birds slim down to reduce joint stress.
- Surgery – In severe, chronic cases surgery may remove damaged tissue and fuse joints.
What is the prognosis for birds with hock issues?
With prompt veterinary care and proper at-home management, many birds show great improvement in their hock condition and are able to make a full recovery. However, hock problems can sometimes persist or reoccur despite treatment in certain cases. Severe, chronic hock may lead to permanent joint damage or disability.
How can bird hock be prevented?
Some recommendations for avoiding hock issues in pet birds include:
- Providing a variety of perch types and diameters to distribute pressure points
- Covering perches in soft material like fleece or vet wrap
- Keeping cage floors clean and dry
- Giving access to areas with soft footing like ropes, swings, or towels
- Maintaining a healthy body weight through proper diet and exercise
- Feeding a balanced diet with omega fatty acids, vitamins and minerals
- Disinfecting perches, toys, and cages regularly
- Avoiding trauma by monitoring cage safety
- Scheduling regular vet exams to catch issues early

Frequently Asked Questions
What birds are most prone to hock issues?
Larger parrots that spend a lot of time on perches seem most susceptible, including cockatoos, Amazons, African greys, and macaws. However, hock issues can occur in any breed if contributory factors are present.
How can I make my bird’s perches safer?
Use perches of varying widths and textures. Cover straight, narrow perches in soft material. Place perches strategically to encourage exercise and distribute weight. Provide rope perches or natural tree branches to allow gripping with the feet.
What foods help bird hock?
Foods rich in omega-3 fatty acids like flaxseed, walnuts, and fish can help reduce inflammation. Fresh fruits and veggies provide vitamins and minerals important for joint health. Calcium and glucosamine supplements also support bones and joints.
Can home remedies be used for mild hock issues?
For very minor irritation, some avian vets recommend home remedies like aloe vera gel, calendula ointment, or epsom salt soaks under medical guidance. But anything beyond mild symptoms warrants an exam and professional treatment.
How often should birds with hock issues be rechecked by a vet?
Your avian vet will advise on the followup schedule, but birds being treated for active hock problems should typically be reexamined every 2-4 weeks to monitor response to treatment and make any needed adjustments.
Are hock issues hereditary in birds?
There does not appear to be a genetic component. However, chronic hock issues in a parent bird may indicate suboptimal cage setup or diet that could also affect offspring if not corrected.
Bird Species | Risk Level |
---|---|
African Grey Parrot | High |
Macaw | High |
Cockatoo | High |
Amazon parrot | Moderate |
Conure | Low |
Budgie | Low |
This table provides a general overview of hock risk levels for some common pet bird species. Individual susceptibility can vary based on specific housing, diet, and activity factors.
Can birds recover fully from hock problems?
Yes, mild to moderate hock issues often resolve fully with proper treatment and management. But severe or chronic cases may cause irreversible joint damage. The sooner treatment begins, the better the prognosis.
How can I help my bird lose weight to relieve hock issues?
Work with your avian vet on a safe calorie-controlled diet plan. Increase exercise by varying cage perches and placing food/water bowls farther apart. Add more vegetables and limit fattening foods. Record weights regularly to track progress.
Example case studies
Case 1
An 8 year old female eclectus parrot was brought to the veterinarian with swelling and crusting around the ankle joints of both feet. The owners noted she had become increasingly reluctant to grip her perches properly. Exam showed ulceration and calluses on the feet in the affected areas. Radiographs did not indicate underlying arthritis. Bloodwork was unremarkable. The bird was started on oral meloxicam for pain and inflammation. The owners were instructed to disinfect and replace cage perches, apply antibiotic cream daily to the feet, and return for rechecks every 2 weeks. After 1 month the hock swelling and lesions were greatly improved and the bird was weightbearing normally.
Case 2
A 5 year old male Timneh African grey parrot was seen for lameness in the right leg. The joint above the foot was reddened, swollen, and painful on exam. Radiographs revealed arthritic changes in the affected joint. The joint capsule appeared thickened. The bird was slightly overweight. Treatment included injectable cartrophen to support joint cartilage, plus oral meloxicam and glucosamine. Cage perches were covered in padding to reduce pressure on the feet. A diet with lower fat and higher omega-3s was recommended. After 6 weeks the bird was much more comfortable standing and gripping, but some joint thickening persisted.
Conclusion
Bird hock is a commonly encountered condition in large parrots and other perching birds. It requires attention to husbandry and diet factors to resolve existing cases and prevent recurrence. Bird owners should monitor their avian companions closely and involve their veterinarian at the first signs of any hock swelling or discomfort. While chronic hock can negatively impact quality of life, excellent outcomes are possible with early intervention. With proper knowledge and care, bird lovers can keep their pets’ feet healthy for years to come.
