Kedleston Hall is a grand stately home nestled in the Derbyshire countryside. In its grounds lives one of the most elusive of British mammals, the stoat. On the estate at the end of winter, we catch a rare glimpse of a stoat in ermine. A visiting shrike, or butcher bird, is another unusual sight. The stately stoats have resided in Kedleston for many years, and each spring an old walled garden is where they choose to raise their young. The kits give a new meaning to the word hyperactive, and their mum is kept busy catching rabbits to feed them. Eventually the stoat family start to explore their estate, where more surprises are in store.
