They wanted to run a way so badly. They had their moment of opportunity, they got through the fence and for the first time, they were actually able to see what life was like on the outside looking in . . .then it occurred to them, not one of them had permission to cross the street. train up a child the way he should go, and he'll not depart from it.
They may not have made a clean getaway, but they did learn a great truth. They had seen the chicken cross the road but no one knew why. Now, because the sheep have learned what the secret is, we can tell others . . .
Why did the chicken cross the road? Because he had permission!!
