These chickens shouldn't be out on the road

"The Chief Veterinary Officers for England, Scotland and Wales have agreed to bring in new measures to help protect poultry and captive birds, following a number of cases of avian influenza in both wild and captive birds in the UK.
The new housing measures, which came into force on 14 December, mean that is now a legal requirement for all bird keepers to keep their birds indoors and to follow strict biosecurity measures in order to limit the spread of and eradicate the disease." (From .gov.uk website)
