What is HPAI (Highly Pathogenic Avian Influenza)?

Highly Pathogenic Avian Influenza (HPAI), also referred to as avian flu or bird flu, is a highly contagious disease caused by the avian influenza virus. It mainly affects birds and can be deadly among backyard flocks. The avian flu can strike suddenly and spread quickly, as we have seen across North America in 2022-2023.

How does Avian Flu spread?

HPAI spreads by direct, bird-to-bird contact and can also spread indirectly when flock members come in contact with contaminated materials. Potential sources of introduction of avian flu into your backyard flock are; poultry products, the transfer of poultry from flock to flock, and migratory birds (including wild ducks and geese.) HPAI can also be spread and moved in manure, egg cartons, farming equipment, and by people who may have inadvertently transferred the virus onto their clothing, shoes, or hands.

What are the signs and symptoms of Avian Flu? 

1. coughing
2. sneezing
3. darkened comb/wattles
4. swelling of the head/eyes
5. nasal discharge
6. lethargy
7. loose droppings
8. drop in laying

 

 

What to do if you think a member of your flock is sick with avian flu.

If members of your flock show signs of illness, isolate and quarantine them from other members immediately. Then contact your local veterinarian or your appropriate state department right away. You can also call the USDA at 1-866-536-7593. Early detection is essential to help prevent the spread of the avian flu.

There is no treatment for HPAI, and if you have a confirmed case of HPAI in your flock, therefore, unfortunately, all members of your flock will need to be put down. Culling is the only way to prevent the spread of the disease to nearby farms and flocks. While it may seem cruel, culling birds with confirmed infection may save the lives of thousands or even millions of other birds and therefore is the only responsible course of action.

 

Tips for preventing Avian flu in your backyard flock - Biosecurity basics 

1. Keep germs away – Always wash your hands before and after coming into contact with your backyard flock. Also, be sure to disinfect any supplies or equipment that comes into contact with your flock.
2. Avoid wild birds – Droppings and fluids from wild birds spread avian influenza. The first and most important rule for you is to practice good biosecurity. This means you can’t allow your flock to drink from or bathe in water sources that wild birds could access, and you can’t allow your flock outdoors unless your run is covered or has an impervious roof. Make sure to quarantine any birds showing signs of infection.
3. Limit visitors to your coop and farm – In Addition, try to avoid any unnecessary visits to your coop or farm. If you have visitors, encourage them to wash their hands and boots or wear gloves and protective boot coverings.

If you think you have come into contact with an infected bird, follow the directions the CDC offers.

How to safely add to your flock during the HPAI outbreak 

In addition, don’t acquire birds from neighbors, friends, your local breeder, or listings on Facebook. You shouldn’t sell your birds to other people, either.

However, you can purchase from NPIP-approved flocks like My Pet Chicken. Why? Because the USDA and State Departments of Agriculture recognize that our breeder flocks are registered and regularly tested for all illnesses, including Avian Influenza. In fact, purchasing from a reputable hatchery or hatching from your own flock is the only safe way to acquire birds at the moment.
