Latest situation gov.uk: " From 18 January 2018, an Avian Influenza Prevention Zone applies to everyone who keeps poultry or captive birds in England. If you keep poultry or birds, you must follow our detailed requirements on strict biosecurity, whether you have commercial flocks or just a few birds in a backyard flock. We have taken these measures because bird flu has now been found in wild birds in this country. Bird flu is also present in Europe, and wild bird migration brings birds to the UK from areas where we know highly pathogenic bird flu is present. We keep our disease control measures under review based on the latest scientific evidence and veterinary advice. Anyone who finds dead wild birds should report them to the Defra helpline on 03459 33 55 77. "

GOV.UK has issued the following biosecurity advice: 

If you keep poultry or other captive birds, you must take action to reduce the risk of disease in your flock by following government advice on biosecurity.
  
Good biosecurity improves the overall health and productivity of your flock by helping keep out poultry diseases such as avian influenza and limiting the spread of disease in an outbreak.  
This applies just as much if you only have a few birds as pets, or if you have a large commercial flock. An outbreak of bird flu in back garden chickens results in the same restrictions on movement of birds. It has the same impact on farmers and trade in poultry as an outbreak on a commercial farm. 


To ensure good biosecurity, all poultry keepers should: 
  • minimise movement in and out of bird enclosures 
  • clean footwear before and after visiting birds, using a Defra approved disinfectant at entrances and exits
  • clean and disinfect vehicles and equipment that have come into contact with poultry
  • keep areas where birds live clean and tidy, and regularly disinfect hard surfaces such as paths and walkways 
  • humanely control rats and mice 
  • place birds’ food and water in fully enclosed areas protected from wild birds, and remove any spilled feed regularly
  • keep birds separate from wildlife and wild waterfowl by putting suitable fencing around outdoor areas they access 
  • keep a close watch on birds for any signs of disease and report any very sick birds or unexplained deaths to your vet
