Autumn Poultry Biosecurity: A Practical Bird Flu Checklist

Autumn is the right time to tighten poultry biosecurity. Migratory waterfowl return to the UK, wet ground makes contamination harder to control, and routine jobs can carry mud and droppings from one area to another. Good habits matter whether you keep a few garden hens or manage a larger smallholding flock.

On 9 October 2026, Defra urged all bird keepers to review and strengthen their arrangements as the seasonal risk of avian influenza increased. The practical measures below turn that advice into a manageable routine.

Check the current rules first. Bird-flu controls can change quickly and may differ between England, Scotland, Wales and Northern Ireland. Disease control zones can also create local requirements. Use the official links at the end of this guide before moving birds, changing access arrangements or relying on an older article.

What biosecurity is trying to prevent

Bird flu can reach kept birds through direct contact with infected wild birds or indirectly through faeces, feathers, carcasses, contaminated water, footwear, clothing, vehicles and equipment. Ducks, geese and other waterfowl are a particular concern because they can carry infection without always appearing ill.

No feeder, bedding product or disinfectant can guarantee protection. The goal is to build several sensible barriers so contamination is less likely to reach your birds.

Autumn poultry biosecurity checklist

1. Register your birds and save the official contacts

In England, keepers must register poultry and other captive birds within one month of keeping them at a premises. Other UK nations have their own services and guidance. Registration helps animal-health authorities contact keepers during an outbreak.

Save the official reporting information on your phone and make sure anyone who looks after the flock knows where it is. Bird flu is a notifiable disease. Suspicion must be reported immediately, even when signs appear mild.

2. Separate feed and water from wild birds

Place feed and water in a covered, enclosed area that wild birds and rodents cannot enter. Do not use open ponds, puddles or collected surface water as drinking water for poultry. Clear spilled feed promptly because it attracts wild birds and pests.

Inspect containers for cracks, standing dirt and areas that are difficult to clean. Our range of poultry feeding and drinking equipment can help when a damaged or unsuitable container needs replacing, but its position and daily cleaning remain just as important as its design.

3. Protect stored feed and bedding

Keep bags and bins covered, dry and inaccessible to wild birds and rodents. Bedding stored outside should be fully covered, and damaged or visibly contaminated packaging should not be taken into bird housing. Sweep up waste and rotate stock so older feed is used first.

Dry housing is easier to manage than damp, compacted litter. Replace wet or heavily soiled areas promptly and keep sufficient clean poultry bedding in protected storage. Store poultry feed separately from chemicals and pest-control products.

4. Create a clean footwear routine

Use footwear that is dedicated to the bird area, or clean and disinfect footwear before entering and after leaving. If you use a foot dip, keep it under cover so rain does not dilute it and leaves or mud do not contaminate it. Replace the solution as directed and use a Defra-approved disinfectant at the approved disease-of-poultry dilution rate, following the manufacturer's instructions.

A disinfectant works as part of a cleaning system, not as a shortcut. Remove visible dirt first, keep clean and dirty equipment apart, and do not walk around the wider holding in footwear reserved for the poultry house.

5. Limit people, tools and vehicle movements

Restrict access to people who genuinely need to enter. Ask essential visitors to follow your clothing and footwear routine. Avoid sharing crates, buckets, barrows and tools between bird areas. If equipment must move, clean and disinfect it before and after use.

Keep a simple visitor and movement record. It can be invaluable if disease is suspected and contacts need to be traced.

6. Inspect housing and outdoor runs

Repair holes that could admit wild birds or rodents, clear blocked gutters, fix leaks and remove places where wild birds can roost above feed or water. Check netting and fencing for gaps. Fence off ponds and standing water and discourage wild birds from gathering around the run.

If your current accommodation needs attention, compare suitable poultry houses and coops with the welfare, ventilation and access needs of your own flock in mind. Do not make a house so sealed that air quality and bird welfare suffer.

7. Keep ducks and geese apart from other poultry

Official guidance recommends keeping ducks and geese in a separate pen or building away from other birds where possible. Do not allow poultry from neighbouring premises to mix with your flock, and prevent shared access to water.

8. Quarantine new or returning birds

Check the health and origin of new birds before purchase. Keep arrivals separate from the established flock in cleaned accommodation, use separate equipment, and change clothing and footwear between groups. Speak to your vet about a suitable isolation period and monitoring plan for your circumstances.

9. Record what is normal

Daily records make unusual changes easier to spot. Note deaths, feed and water consumption, egg production, and movements of birds and eggs on or off the premises. Look at the flock as a group as well as checking individual birds.

Signs that need urgent action

Possible signs of highly pathogenic avian influenza include sudden death, marked lethargy, reduced appetite, a sharp fall in egg production, breathing difficulty, watery or discoloured droppings, swelling of the head, blue discolouration of the comb or wattles, and loss of coordination. Not every bird shows every sign, and only laboratory testing can confirm the disease.

If you are worried about the health of your birds, speak to your vet. If you suspect bird flu, report it immediately through the official service for your nation. Do not move birds, eggs, manure or equipment off the premises while waiting for advice.

A five-minute daily autumn check

• Are feed and water protected from wild birds?
• Has spilled feed been removed?
• Are footwear controls clean, covered and ready to use?
• Are fences, netting, roofs, gutters and drains intact?
• Is bedding dry and stored securely?
• Are feed intake, water intake and egg numbers normal?
• Are all birds alert, moving and breathing normally?
• Do current national or local restrictions affect the premises?

Biosecurity is most effective when it is routine. A short check every day is easier and safer than trying to correct several weaknesses after disease risk has already risen.
