The Importance of Biosecurity for Your Chickens

Updated: Sep 27


Chicken in the grass

When I started back up with raising my current flock (I took a couple years off), I was pretty set on only having 6 chickens. Now, fast forward almost 3 years and my flock is up to 40! Hahaha! If you know what chicken math is, that’s why!


Why Adding Adult Chickens Can Be Risky

I am part of a number of backyard chicken groups on social media and it seems there are always people selling or giving away chickens or looking to add adult birds into their flock. As tempting as some of these beautiful birds are, I always decline. Some of the best advice I ever received was from Dr. Bob Stock, a brilliant poultry nutritionist. He told me that if I wanted to add to my flock, just add them as chicks.


Obviously, there’s a process to adding to your flock that way and you can read my other blog here about integrating your new chicks into your current flock.


What Is Biosecurity?

So, what exactly is biosecurity? According to Merriam-Webster, biosecurity is “security from exposure to harmful biological agents” and refers to the measures taken to ensure this security. In simple terms, biosecurity is about keeping your flock healthy and preventing them from being exposed to diseases, pests, and other harmful elements.

Common Threats to Your Flock’s Biosecurity

Biosecurity may sound complicated, but it’s about keeping your chickens safe. Here are some common threats to watch out for:


1. Adding Mature Birds

As mentioned, adding adult birds to your flock can introduce diseases or pests like lice and mites. If you must add mature birds, it’s essential to quarantine them for 30 days before introducing them to your flock. During this time, check them for pests and disease. Some chicken keepers have had success with this process, but others have faced severe issues like lice infestations or even disease outbreaks that wiped out their flocks.


2. Contaminated Shoes

Believe it or not, your shoes can pose a risk to your flock! If you walk through contaminated areas, you can track harmful bacteria or parasites into your coop. I always wear the same pair of shoes when entering the coop—one pair for summer and another for winter. If I visit someone else with chickens, I avoid wearing my “chicken shoes,” and I ask visitors to do the same. This simple step helps protect my flock from unwanted contaminants.


3. Wild Birds and Rodents

Wild birds and rodents can also introduce lice, mites and diseases to your flock. If your run or coop isn’t secure, these pests can easily get in and create problems. While I haven’t had issues yet, I know it’s something to be mindful of, especially since my run isn’t covered. To minimize risk, I keep my chickens inside the run and rarely let them free-range, reducing exposure to wild animals.


Securing Your Coop and Run

Securing your coop and run is one of the most effective ways to ensure biosecurity. Make sure your setup is sturdy and safe from intruders like wild birds and rodents. If you live in an area with predators, like I do, consider installing a large, secure run rather than free-ranging.


Biosecurity for New Chicken Keepers

For new backyard chicken keepers, biosecurity can seem like a big, overwhelming word. But it’s simply about keeping your flock healthy and preventing problems before they start. By following these tips and ensuring your chickens are on a proper diet with immune system support (like using Chicken Essentials), you’ll be taking the right steps to protect your flock!


Until next time,
