Where can I watch Duck Dynasty in United States?

At first glance the Robertsons look like a typical Louisiana family who lives for duck hunting season. A closer look, however, reveals they live very well because of duck hunting season. The Robertsons own and operate Duck Commanders, which specializes in fabricating duck calls and decoys out of salvaged swamp wood. The company has grown from a mom-and-pop operation to a multimillionaire sporting empire, established in 1973 by family patriarch Phil (aka the Duck Commander) and now run by his business-savvy son, Willie. "Duck Dynasty" follows the Robertsons and their booming business, which also employs Willie's wife, Korie, his brother Jase and Uncle Si, a Vietnam vet and colorful character who keeps the guys in the workshop occupied with his many stories.
