Avian influenza, also known as bird flu, is a highly contagious viral disease that affects birds. While it is not very common, outbreaks can occur in domestic poultry flocks and wild bird populations. The risk of avian influenza depends on several factors, including the specific strain of the virus, the geographic location, and biosecurity measures in place for poultry flocks.
If your chickens free range around wild birds, there is a risk that they may come into contact with the avian influenza virus or other diseases. However, this risk can be minimized by implementing proper biosecurity measures, such as keeping your flock away from wild bird populations when possible, keeping the coop and surrounding area clean and sanitized, and preventing visitors or equipment from coming into contact with your flock without proper disinfection.
It's also important to monitor your flock for signs of illness and to consult with a veterinarian if you suspect that your chickens may have been exposed to avian influenza or any other diseases. By taking appropriate precautions and seeking veterinary care as needed, you can help to keep your flock healthy and minimize the risk of disease.
