Germ Buster Biosecurity – How To Keep Your Backyard Chickens Healthy
keeping Backyard Chickens Safe Starts with Biosecurity
Raising chickens is incredibly rewarding—but it’s also a responsibility. Whether you have two hens or twenty, keeping your flock healthy starts with something many new keepers overlook: biosecurity.
Bio-what? Security-who?
Put simply, biosecurity means keeping germs and disease *out* of your coop. It’s not about fear—it’s about prevention. A few simple habits can protect your birds from common threats like avian influenza, Newcastle disease, respiratory infections, mites, and more.
Why Biosecurity Matters for Small Flocks
Even if your flock never leaves your backyard, they can still be exposed to disease. Germs hitch rides on shoes, tools, wild birds, feed bags, and even well-meaning visitors. Chickens themselves may not always show signs of illness right away, which makes it easy for disease to spread unnoticed.
Unlike large commercial farms, backyard flocks do not have dedicated staff, foot baths, shower-in facilities, or controlled access. You are your chickens’ first line of defense. That’s why **simple, everyday biosecurity practices** are even more important for small-scale keepers.
7 Simple Biosecurity Practices That Work
1. Wash Your Hands and Boots
Always wash your hands before and after handling chickens, eggs, feed, or bedding. Keep a designated pair of boots (or disposable boot covers) for the coop area. Don’t wear your coop shoes into your house or barn.
Listen to your mother – wash your hands, take off your shoes, don’t be gross!
2. Don’t Share Equipment Between Flocks
If you have friends with chickens, resist the urge to lend or borrow feeders, waterers, cages, or tools. Viruses and bacteria can hide in the cracks and crevices of shared gear. If you must share, thoroughly clean and disinfect before and after use. Remove all organic material before you disinfect. Remember, you cannot disinfect poop and litter!
3. Quarantine New Birds
Bringing home new chickens? Keep them separated from your flock for at least **30 days**. Watch for signs of illness—like sneezing, runny eyes, diarrhea, or lethargy. Quarantine isn’t overkill; it is smart flock management.
Quarantine birds should have their own dedicated run, feeders, and waterers. Work with your new birds last each day, to avoid tracking germs to your established flock.
4. Keep Wild Birds Out
Wild birds can carry serious diseases, even if they look healthy. Keep feed and water covered to discourage songbirds, and avoid feeding wild birds near your chicken area. Repair holes in netting or fencing to prevent access.
Locate your coop as far away as possible from ponds and waterways. They attract wild waterfowl. And for Pete’s sake, do NOT feed the wild ducks and geese! They carry bird flu!
5. Limit Visitors and Use Personal Protective Equipment (PPE)
Everyone wants to see the chickens—but not everyone should walk through your coop. Visitors can unknowingly bring in germs from other farms or feed stores. If someone must enter, offer them a boot wash or disposable shoe covers. Cheap, easy, disposable PPE!
It sounds like overkill, but that foot bath of dilute bleach goes a long way. Don’t forget to set out a boot brush. You cannot disinfect packed dirt and debris! De-gunk before you dunk!
6. Clean and Disinfect Regularly
Clean coops and equipment often. Remove droppings, old bedding, and dirty feed. Disinfect feeders, waterers, and tools regularly with a mild bleach solution (1 part bleach to 9 parts water). Let them air dry completely before reuse. Scrub, scrub, scrub!
7. Keep an Eye on Your Flock
You know your birds best. A healthy flock is active, alert, and eats well. If you notice a bird acting “off” — isolate them early, monitor symptoms, and contact a vet if needed. Early action helps stop spread.

What About Shows, Swaps, and Sales?
Exhibiting or buying chickens at fairs, swaps, and sales? As a public health veterinarian, poultry shows and live bird markets give me heartburn. But for chicken enthusiasts, they are so fun! Just be extra careful. Events with lots of birds from different sources increase the risk of disease exposure.
Use these tips:
– Keep your birds in cages and avoid direct contact with others
– Don’t share waterers or feeders at events
– Quarantine birds again when you return home
– Change clothes and shoes after attending an event—even if you didn’t bring birds
