Good morning,
The council have been advised that the government have declared a prevention zone across all of Great Britain, which came effective from the 3rd November and means that all bird keepers (whether they are pet birds, commercial flocks, or just a few birds in a backyard) are required by law to take a range of biosecurity measures. The measures can be found on the following website:

Have a nice day.
