BIRD FLU UPDATE
Tues 11th Nov 2025: The APHA have announced that due to an increase in cases of Bird flu, they have extended the housing measures, like England below, to cover Wales from 00.01 on Thurs 13th Nov.
Tues 4th Nov 2025: Following an increase in the number of cases over the last week in the previous areas listed, mostly commercial premises, now including Mid Devon, the APHA have announced the following:
There are some areas in the AIPZ in England where you already have to house your birds. From 00.01 on Thurs 6th November 2025, mandatory housing measures will be extended to the whole of England (for the criteria below^).
Note again: You do not have to house your birds if you keep less than 50 birds and their eggs or poultry products are for your own use only.
28th October 2025: Just to clarify APHA announcement today (because, as normal, it's not that clear) ...
^You must house your birds IF:
- You live in the counties listed below* and on gov.uk here,
AND:
- You have 50 birds or more.
- You have less than 50 birds and SELL or GIVE AWAY your eggs, live birds or birds as food (meat products).
APHA announced on their website: "From 00:01am on Thu 30 October 2025, there will be some areas of the AIPZ in England where you must house your birds if you keep either:
* more than 50 birds of any species
* any number of poultry (meaning birds that are kept to give away or sell eggs, poultry products or live birds).
You will not have to house your birds if you keep less than 50 birds and their eggs or meat are for your own use only.
These additional housing measures will apply in the high-risk counties listed to help protect your birds from bird flu."
Since 25th Jan 2025, the APHA has had an Avian Influenza Prevention Zone, meaning mandatory biosecurity measures, in place across the whole of England, Scotland & Wales. To clarify - this is not a housing order, it is a mandatory biosecurity order (disinfectant footbaths outside your poultry pens, reduce contact with wild birds, cover food and water, etc)
* Cheshire, Cumbria, Derbyshire, Durham, East Riding of Yorkshire, Greater Manchester, Lancashire, Leicestershire, Lincolnshire, Merseyside, Norfolk, North Yorkshire, Northumberland, Nottinghamshire, Rutland, Shropshire, South Yorkshire, Staffordshire, Suffolk, Tyne and Wear, West Yorkshire
Avian Influenza (Bird 'Flu) - Key Information from THE ANIMAL & PLANT HEALTH AGENCY (APHA)
Definitions of the APHA Zones
Avian Influenza Prevention Zone (AIPZ): A broad area (often country-wide) covering all bird keepers in which enhanced biosecurity rules apply to prevent bird flu spreading from wild to captive birds.
Surveillance Zone: A specific radius-based zone (e.g. 10 km around an infected poultry site) where extra movement controls apply, but housing of birds isn’t always required.
Housing Order: A legal requirement for all poultry and captive birds in a defined area to be kept indoors (or fully protected from wild birds) because the risk of avian influenza is very high.
It is perhaps a quirky thought, but a large umbrella for your free-ranging chooks just won't be the answer to keeping them safe from Bird Flu.
The Animal & Plant Health Agency (APHA) is an executive agency run by the government's Department for Environment, Food & Rural Affairs (DEFRA).
Information from the APHA website - This information tells you what you must do if you keep birds in the UK and an Avian Influenza Restriction or Prevention Zone is in place.
If you keep poultry, you must, by law, follow specific disease prevention measures. These apply to all keepers of birds, regardless of flock size or whether your birds are pets. See also our information about Registration of Flocks.
The AIPZ biosecurity measures are designed to reduce the risk of infection from wild birds. If you keep poultry of any kind, then you can continue to allow your birds outdoors into fenced areas, but only if these areas meet certain conditions, including:
- You have made the areas unattractive to wild birds, for example, by netting ponds and by removing wild bird food sources.
- You have taken action to reduce any existing contamination, such as cleaning and disinfecting concrete areas, fencing off wet or boggy areas, as well as disinfecting feeders and drinkers.
- You have assessed the risk of your birds coming into contact with wild birds or contamination from them.
- You have restricted access to the birds' area to only essential visits and added a disinfectant footbath near the entrance to use whenever entering or exiting the area.
- You should make every effort to eradicate rodents from the area.
If you keep more than 500 birds, you must take some extra biosecurity measures. They include identifying clearly defined areas where access by non-essential people and vehicles is restricted and cleaning and disinfecting vehicles, equipment and footwear.

As you may know, the Bird 'Flu (Avian Influenza) disease can spread from bird to bird by direct contact or through contaminated body fluids and faeces. The main risk of infection is likely to come from wild birds using the same ground and feeders as your poultry.
You should also make every effort to eliminate rodents. They can equally carry contamination in and around your chicken runs. We hope this simple FAQ checklist will answer your most common Bird 'flu concerns. The bio-security products can be found in our Disinfectants Section.
What are the signs of Bird Flu?
As advised by APHA, these are the signs we should look for in our chickens, or if you notice any wild birds displaying such symptoms (it is advisable not to touch infected or dead birds whenever possible unless wearing gloves and a mask).
Highly pathogenic avian influenza (HPAI) H5N1 is the more serious type. It is often fatal in birds. The main clinical signs of HPAI in birds (which can include any or a combination of the following) are:
- the sudden and rapid increase in the number of birds found dead
- several birds were affected in the same shed or airspace
- swollen head
- closed and excessively watery eyes
- lethargy and depression
- recumbency and unresponsiveness
- incoordination and loss of balance
- head and body tremors
- drooping of the wings and/or dragging of legs
- twisting of the head and neck
- swelling and blue discolouration of the comb and wattles
- haemorrhages on the shanks of the legs and under the skin of the neck
- loss of appetite or marked decrease in feed consumption
- sudden increase or decrease in water consumption
- respiratory distress such as gaping (mouth breathing), nasal snicking (coughing sound), sneezing, gurgling or rattling
- fever or noticeable increase in body temperature
- discoloured or loose watery droppings
- cessation or marked reduction in egg production
- Clinical signs can vary between species of birds, and some species (for example, ducks and geese) may show minimal clinical signs.
Please note that many of these symptoms are also indicative of other less serious diseases. Vigilance is everything.
What does APHA (DEFRA) mean by 'keep birds inside'?
When the APHA announce a 'Housing Order', this means that 'birds must be kept inside', but what exactly does this mean?
The advice to keep birds 'inside' can mean just keeping your birds confined to their run, but the run should have a covered roof.
If you don't currently have a Run or Pen, you could construct an inexpensive temporary one from, perhaps, old pallets and small mesh wire, in the short term.
The main concern is to ensure that wild birds cannot access the run. Any holes in the fence or wire need to be small (e.g., half-inch by one-inch mesh will keep wild birds out).
A Housing Order means that the roof of the run should be covered. This can be with anything from a Polycarbonate Roof or a translucent tarpaulin attached securely.
For ideas about the ideal chicken run, take a look at Poultry Protection Pens or Free Standing Runs. We have many sizes and styles to suit a range of budgets and house styles. There are options to fix to a Flyte so Fancy house or one of your own.
If the roof of your Pen is open to the elements, then passing birds can land on it, or fly over, and any excretions will land inside the run. This has to be prevented in an Avian Prevention Zone. The best way to prevent droppings from wild birds that might have been exposed to avian flu would be to cover your existing run to create a 'roof'.
The simplest and most cost-effective solution is to use a tarpaulin, readily available from many DIY stores. Our PVC Rainshades are ideal for this and available in 3 sizes. A more permanent solution could be to cover the roof with polycarbonate sheets or other lightweight roofing materials, which are also available from builders' merchants or from our website.
A little tip here is to try and make sure that by adding a roof covering, you are not making the run too dark for the birds. They do need as many good daylight hours as possible to be healthy and produce good eggs.
What if I have to confine my birds to their house?
If the APHA announces a restriction, it applies to all poultry and captive birds. For some of us, it is just not practical to create an outdoor covered run area. In this instance, birds will need to be confined to their hen house.
More frequent cleaning will help to keep the birds healthy. Using products such as Stalosan F Sanitising Powder will help reduce the build-up of moisture created by the condensation of having birds in a confined space.
Using HempBed-E Bedding, which is super absorbent and contains eucalyptus, will also help reduce humidity and keep the air fresher.
In this case, you might also have to consider adding a light to the house too. Set it to come on during certain hours so that you can replicate daylight.
Another consideration is that bored, tightly confined birds start to get restless and bully each other, leading to feather pecking or injury.
To help prevent this, we would recommend placing items inside to act as a distraction. Try our Boredom Buster blocks or perhaps a few items to peck at, such as hanging up a cabbage. See more hanging treats.
Feeders and Drinkers will need to be kept inside (or undercover), away from contamination. Hanging feeders may be an easy option, helping to keep the bedding dry and minimise the amount of spilt food in such a confined area.
Which Disinfectant can I use against Bird flu?
There are many poultry disinfectants on the market, but not all are specifically approved by DEFRA for use against Avian Influenza.
The most popular one is Virkon S Disinfectant, which comes in tablet or powder form (to be dissolved in water). These can be used for cleaning the house, feeders and drinkers (rinse well with fresh water) and for creating a simple foot bath.
A disinfectant footbath can be a container like a washing-up bowl to a tub trug, filled with a disinfectant solution. Everyone should use it on entering and exiting the poultry area. Try our Recycled Tyre Troughs as a cheap but robust footbath.
Virkon S Tablets are cost-effective when small quantities are needed, as once made up, the solution can be stored. One tablet makes 500ml of solution.
The Virkon Sachet is also useful for footbaths as it makes 5 litres of solution, which can stay in a footbath and be reused many times before needing replacing.
Protective clothing and disposable gloves and masks are practical considerations when handling your birds and cleaning their enclosures to avoid spreading any potential contamination.
