What are the Symptoms of Avian Flu in Birds?

Highly pathogenic avian influenza (HPAI), also known as bird flu, is a fast-spreading and often deadly virus affecting poultry. Early detection is critical to protecting your flock and preventing the spread of this disease. Knowing the symptoms of HPAI can help you take quick action if your birds show signs of illness.

Here’s what to watch for and what to do if you suspect HPAI in your flock.

Common Symptoms of Avian Influenza in Birds

HPAI can cause a variety of symptoms, ranging from mild to severe. Some birds may show subtle signs of illness, while others may become seriously ill very quickly.

Signs of HPAI to Look For:

• Respiratory Issues – Coughing, sneezing, and nasal discharge are early signs of illness.
  
• Swollen Head or Eyes – Swelling around the face, eyes, or neck can indicate infection.
  
• Darkened Comb or Wattles – A purple or dark discoloration of the comb, wattles, or legs may appear.
  
• Lethargy & Reduced Appetite – Birds may become unusually inactive or refuse to eat.
  
• Loose Droppings – Diarrhea or abnormal droppings can be a symptom of infection.
  
• Decreased Egg Production – Hens may stop laying or produce fewer eggs.

Since HPAI spreads rapidly, it’s essential to monitor your flock closely and take immediate action if you notice these symptoms.

What to Do If You Suspect HPAI in Your Flock

1. Quarantine Sick Birds Immediately – Separate any birds showing symptoms from the rest of the flock to prevent further spread.
   
2. Contact the Experts – Reach out to your local veterinarian, state agricultural department, or the USDA hotline at 1-866-536-7593 for guidance.
   
3. Increase Biosecurity Measures – Clean and disinfect coops, equipment, and clothing to reduce the risk of spreading the virus.
   
4. Limit Flock Exposure – Avoid contact with other poultry keepers and prevent wild birds from accessing your flock’s food and water.

Because HPAI has a high mortality rate, fast action is crucial. If you suspect an outbreak, reporting it quickly can help protect other flocks in your area.

Stay Informed & Protect Your Birds

Recognizing the symptoms of HPAI early can make a difference in stopping the spread. Stay vigilant, practice good biosecurity, and monitor your birds closely.
