When I was young, I was out walking near a farm in Devon and came across a dead lamb. It had got stuck in some deep mud near the edge of the field, and probably drowned – only half of it’s head was visible. Just as I walked past, a huge arse crow plucked one of it’s eyeballs out. The sound of it coming out has completely stayed with me all these years; one of those really vivid memories that comes back to you at 4am when you can’t sleep.
