I see the National Sheep Association, CLA, NFU & others have joined in asking sheep keepers to take part in a survey at the end of lambing (or each lambing period if you lamb in batches). You don't have to be a member of any of those organisations - the objective is to get a clear picture of what's happening and where, since DEFRA seems to be keeping its head well below the parapet on this one. It can be found at:
