Biosecurity Tips for Chickens for A Healthy Flock

I am not someone to jump on the bandwagon and freak out over things. I am not going to panic over things that I cannot change. There are things that we do no matter the possibility of avian flu to keep our flocks safe.

At all times we:

do not free range
do not let other people into our runs/coops

Here are 7 practical biosecurity tips for chickens to help you and other backyard chicken keepers reduce health risks and maintain a healthy flock year-round.

Quarantine New Birds Before Introducing Them to Your Flock

Adding new chickens to your flock? Always isolate them for at least 30 days before allowing them into the main chicken area. This simple step helps prevent the spread of diseases through direct contact. Watch closely for signs of illness, such as coughing, lethargy, or changes in droppings.

Good practice tip: Set up a separate coop or temporary enclosure far from your main flock during the quarantine period.

I know it can be hard to do this, one to wait that long, and two to have the space available to do it, and a lot of chicken owners just don't do it. It is a huge risk to take.

Limit Exposure to Wild Birds and Animals

Wildlife, especially migratory waterfowl, often carry disease-causing organisms that can infect your domestic poultry. Prevent them from accessing your chicken coop, water sources, and feed.

Remove wild bird feeders near your poultry site
Cover runs with netting to reduce contact with wild birds
Secure feed in containers to deter small animals

Covering your runs can also help with the mud that comes in the Spring, too! I miss having covered runs because there is one out of our 4 runs that is ankle deep when we get a good amount of rain. Springtime is a mess out there.

Use Footwear in the Chicken Yard

Before entering your poultry houses or chicken yard, wear a dedicated pair of shoes or boots. This helps reduce disease transmission from human movement between coops, pastures, and public areas.

Tip: Keep a boot brush and disinfectant tray at coop entrances. Change into your chicken shoes when you arrive at the poultry site.

We do have boots that are only worn for the chicken coops because as I mentioned before… mud, and poop too, I don't want it tracked into my house or vehicle.

Clean and Disinfect Equipment Regularly

Farm equipment, waterers, and feeders should be cleaned frequently to prevent the spread of the disease. Even organic material like soiled bedding or manure can harbor pathogens.

Scrub waterers weekly with vinegar or bleach solution
Replace dirty litter regularly
Don’t share tools between coops or with other poultry producers

Minimize Visitors and Control Traffic Around the Coop

Only allow trusted visitors into your chicken space. Traffic control is a core part of any biosecurity plan.

If visitors must enter:

Provide disposable protective clothing
Require a biosecurity footbath or boot change
Keep a visitor log (especially useful for poultry shows)

Monitor Your Flock Daily for Health Issues

Early detection of contagious illnesses is one of the most important ways to keep a flock safe. A sudden increase in deaths, changes in behavior.

Watch daily for:

Sneezing, nasal discharge
Lethargy or drooping wings
Swelling around the eyes or head

Stay Informed and Follow Local Guidelines

The USDA and the Plant Health Inspection Service (APHIS) provide updates on outbreaks like avian flu and exotic Newcastle. Follow local regulations and register your flock if required in your state.

Poultry keepers should stay connected to their regional extension offices, poultry health programs, and participate in NPIP (National Poultry Improvement Plan) if possible.

Having a strong biosecurity plan isn’t just for large poultry farms—it’s a best practice for every flock, big or small. These biosecurity measures help prevent disease spread, protect your healthy chickens, and safeguard the entire poultry community.

Whether you’re raising backyard chickens or managing a small homestead, biosecurity plays an important role in the long-term health of your flock.
