Biosecurity Measures For Poultry June 2022

Biosecurity Measures For Poultry

Declaration of a Protection Zone and a Surveillance Zone (H5N1 Highly Pathogenic Avian Infuenza) near Bexhill-on-Sea, Rother, East Sussex...

Following an outbreak of bird flu a Protection Zone and Surveillance Zone has been placed around Bexhill On Sea:

The Protection Zone is a 3km radius, centred on grid reference TQ760709040 Bexhill-on-Sea
The Surveillance Zone is a 10km radius, centred on grid reference TQ760709040 Bexhill-on-Sea

A map showing the 3km and 10km zones is available on the Gov.​UK site at:

Birds within the 3km zone should be kept housed, not outdoors.
Birds within the 10km zone can be allowed outdoors but there is no movement of birds or eggs within the 10km surveillance zone (except under license) and strict biosecurtiy measures must be followed.

Avian Influenza Prevention Zone

An Avian Influenza Prevention Zone (AIPZ) is in force across Great Britain.

This means, all bird keepers across Great Britain (whether they have pet birds, commercial flocks or just a few birds in a backyard flock) must follow strict biosecurity measures to limit the spread of and eradicate the disease.

You are no longer required to house your birds (please refer to the Bexhill zones above). However, you must continue to house your poultry and other captive birds if they are in a protection zone. For details of the cases and the measures that apply in the disease control zones in England, see the avian influenza: cases and disease control zones in England guidance.

Failure to comply with the AIPZ is an offence and risks the health and welfare of your birds.

The AIPZ in England means that bird keepers must:

  • cleanse and disinfect clothing, footwear, equipment and vehicles before and after contact with poultry and captive birds – if practical, use disposable protective clothing
  • reduce the movement of people, vehicles or equipment to and from areas where poultry and captive birds are kept, to minimise contamination from manure, slurry and other products, and use effective vermin control
  • thoroughly cleanse and disinfect housing on a continuous basis
  • keep fresh disinfectant at the right concentration at all farm and poultry housing entry and exit points
  • minimise direct and indirect contact between poultry and captive birds and wild birds, including making sure all feed and water is not accessible to wild birds

To help bird keepers comply Defra have updated the biosecurity advice .


Mantel Farm’s Help And Advice

For Good Biosecurity

  • Minimize movement in and out of bird enclosures:

There is no need to stop enjoying time with your flock, however, plan your visits.  Combine visits with essential care such as providing food and water, checking all is well and egg collecting.  Always practice good hygiene.


  • Clean footwear before and after visiting birds, using a Defra approved disinfectant at entrances & exits:

Set up a simple footbath near the entrance to your chicken run (a large bucket or tub-trug is ideal) with a solution of Defra approved disinfectant.  We recommend BioVX, a UK Defra approved powder.  A separate set of footwear is also advisable and keeps things really simple.  Keep the solution clean, changing regularly.


  • Keep areas where birds live clean and tidy, and regularly disinfect hard surfaces such as paths and walkways:

Keeping any livestock area clean and tidy is key to good poultry health, not only will it meet the Defra requirements, but it will make their care more pleasurable and help to prevent all poultry pests and diseases. 

There are many disinfectants available for poultry keepers and being conscious of the environment we have always recommended the more natural products available, steering away from the unnecessary use of harsh chemicals.  This we continue to do and our recommended products for general day to day cleaning are Poultry Shield and BioDri.  However, there is a place for stronger disinfectants and periodically (say monthly) you should give the poultry house a thorough clean with a Defra approved product such as Bi0 VX. 

Keeping the ground of your pen clean and dry, also plays an important part in maintaining the biosecurity and comfort of your birds.  No birds are happy in wet muddy conditions. A simple answer is to provide a thick layer of woodchips across the run. This gives the birds a surface to scratch around in and keeps the floor dry, so making it easier for your access also.  We recommend applying BioDri to the outside pen, this super-absorbent powder extends the life of the bedding and is a fresh smelling powder that is nonhazardous.


Application of Poultry Shield:

Make a litre of solution by adding 200ml of Poultry Shield concentrate to 800ml of water.  To clean, sanitise and odour neutralise your coop:

Remove old bedding and excess litter

Spray interior areas and equipment with poultry shield solution.  Pay particular attention to the roof structure, joints, cracks, crevices and perches. 

Leave to soak for 1 hour, then brush clean.

Application of BioDri:

A fresh smelling nonhazardous powder suitable for use with animals and birds of all ages.

This powder is extremely effective in absorbing liquids and ammonia gas, inhibiting the growth and spread of bacteria and other harmful organisms. 

Add 1 cup per square meter on top of the animal bedding.

Application of BioVX:

BioVX is broad spectrum and effective against bacteria, fungi, yeasts and all known classes of virus. Being Defra approved and bio-degradable, its superior dilution rates make it a highly cost-effective solution for foot baths.

Dilute 1:200 in a suitable container to act as a footbath.


  • Humanely control rats and mice:

Preventative measures for rodent control are essential, being able to act early, knowing how to prevent and control a rodent infestation is key.  New laws came into effect in April 2016, restricting certain rodenticides to professional certified users only.  This has meant a change to the products available for 'garden farmers' to purchase.  Pack sizes are now limited to 1.5kg, however, we can still offer a range of products from bait stations, pastes, blocks and traps. With a controlled approach these pack sizes should be enough to keep rodents under control, and if they are not successful a professional pest controller should be consulted. More information can be found on the CRRU website:


  • Place bird food and water in fully enclosed areas protected from wild birds, and remove any spilled feed regularly:

Unless there is a full restriction zone in your area, a Defra prevention zone does not require you to keep your birds in a fully enclosed run, it does however require you to feed your flock in fully enclosed areas.  This seems a little tricky; as if your hens can get out of the area it would seem possible for wild birds to enter.  You must therefore do your best to ensure the feed and water containers are placed undercover to prevent access or contamination by wild birds.  Placing feed on the ground or in uncovered troughs to which wild birds can gain access is not permitted.


The ideal solution to this is to have a fully enclosed run adjacent to your poultry house.  This is something we always recommend to new poultry keepers, as there are many benefits of such a setup.  Ideally, this run would have a solid (e.g. Onduline) roof, or be covered in netting or willow screening.  Screening also works well around the sides of the run, preventing wild birds from accessing larger mesh.  This run can then (if large enough) be used to keep your flock in permanently, or if you like to free-range your birds, the door can be opened in controlled times when feeders can be removed.

Spilled feed can be kept at a minimum by using a purpose-made poultry feeder.  We recommend the types that are filled from the top with anti-scratch fins around the base.  Avoid mixing your feed, birds are selective and will pick out the best bits, flicking the other on the floor.  Keep corn as a treat, fed separately from the main feed.  Feeders with adjustable fin height mean you can also restrict the flow of feed to minimize wastage.  Where possible always hang your feeder, if this is not possible then place the feed off the floor on bricks or concrete blocks.  Don’t forget to regularly clean your drinkers and feeders, Poultry Shield is ideal for doing so.


  • Keep birds separate from wildlife and wild waterfowl by putting suitable fencing around outdoor areas they access:

Where birds are free-ranging, the Defra guidelines are as follows:

  • Outdoor range areas (all outdoor areas where poultry have access) must be fenced to keep birds within the range and must be actively managed by the keeper to ensure that the range area is not contaminated with feathers or faecal material from wild birds and take all reasonable steps to remove such contamination that may be present;
  • Access to open or standing water is restricted by fencing off and netting ponds, standing water, or waterlogged land to prevent access by poultry or other captive birds;
  • There is no direct contact with poultry or other captive birds on other neighbouring premises;
  • Feed and water are kept and birds are fed indoors or under a covered area which sufficiently discourages the landing of wild birds and thereby prevent contact by wild birds with their feed or water;
  • Wild birds are not attracted to the vicinity of the outdoor area, in particular to standing water or ponds;
  • Measures are taken to discourage wild birds, in particular gulls and wild waterfowl, from entering the fenced outdoor areas;
  • Any carcases of wild birds are removed from the outdoor fenced range area; and
  • There is regular cleaning and disinfecting of all concrete walkways, paths and similar surfaces to which poultry or other captive birds or wild birds have access.


  • Keep a close watch on birds for any signs of disease and report any very sick birds or unexplained deaths to your vet:


Bird flu is a notifiable animal disease. If you suspect any type of bird flu you must report it immediately by calling the Defra Rural Services Helpline on 03000 200 301.

If you keep poultry, you should keep a close watch on them for signs of disease, and maintain good biosecurity at all times. If you have any concerns about the health of your poultry, seek prompt advice from your vet.


How to spot avian influenza:

There are 2 types of avian influenza.

Highly pathogenic avian influenza (HPAI) is the more serious type. It is often fatal in birds. The main clinical signs of HPAI in birds are:

  • Swollen head
  • Blue discolouration of neck and throat
  • Loss of appetite
  • Respiratory distress such as gaping beak, coughing, sneezing, gurgling, rattling
  • Diarrhoea
  • Fewer eggs laid
  • Increased mortality


Clinical signs can vary between species of bird and some species (for example ducks and geese) may show minimal clinical signs.

Low pathogenic avian influenza (LPAI) is usually less serious. It can cause mild breathing problems, but affected birds will not always show clear signs of infection.

The severity of LPAI depends on the type of bird and whether it has any other illnesses.

Please remember the above signs are guidance only, and unfortunately many of them are common in other poultry issues and behaviour – for example ‘Fewer laid eggs’ can simply mean the bird is having a rest, moulting or it is a breed that just goes off lay in the winter. 

So, our advice is: don’t panic, but know your flock, enjoy your birds, and act responsibly.
