Bird flu has been found in a sheep for the first time. DEFRA said the case in Yorkshire was on a farm where avian flu was present in captive birds. One ewe tested positive and has been culled, but her lambs and the rest of the small flock of sheep were negative. Surveillance of mammals for avian flu has been stepped up, partly because in the United States many dairy cattle and even some dairy workers, have gone down with the disease. We speak to the chief vet.

Avian influenza is of course at the forefront of egg producers' minds at the moment, and free range layers in many parts of the country must now be kept indoors. All week we're taking a closer look at egg production. Today we speak to a free-range egg producer in Wales.

A project involving farmers and nature conservationists is celebrating the restoration of 400 "lost" farmland ponds in Essex. A century ago there were more than 17,000 in the county but conservationists say around 10,000 of those have disappeared. We visit a farm which has been part of a big project to restore some of them.
