Bird flu is continuing its spread, with an ever growing list of English counties - and the whole of Northern Ireland – now under restrictions which mean all poultry has to be kept indoors. And stricter bio-security measures have been imposed across the whole of the UK.

We hear from a farmer in Devon who has had to cull his birds because of a disease outbreak. And the chair of virology at Edinburgh University’s Roslin Institute, Professor Paul Digard, discusses the avian flu vaccine situation in the UK and elsewhere.

Our theme this week is bulbs - Spring isn't far away! We're with daffodil pickers near Truro in Cornwall.
