It’s like a real-life version of the movie “Chicken Run,” only without Mel Gibson and much, much slower. Near Summerville, Georgia, there is a turtle farm. Thousands of adult turtles, all native species to the southern United States, live in ponds on the property. Thanks to vandals or scrap metal thieves, breaks in the fence have allowed the turtles to wander off the property, taking up residence in surrounding waterways. The operation is something like a hatchery, and about 1,600 of the 2,200 turtles that form its breeding stock have run away.
