Beyond the fence

The tall-walkers have ceased delivering food and water. Hunger rattles the flock. Deep down, they all know their only chance of survival is escape. Witness them brave the unknown wilderness in a desperate attempt to decide to forge their own destiny- although, like a shadow, the disappearance of their owners lurks like a vulture over the flock. Danger is near. (Edit- This is a work and progress, so this will take a while)
