Like millions of Americans, I’ve become a “Duck Dynasty” fan.“Duck Dynasty,” as you surely are aware, is an A&E reality show that presents the Robertson clan, the long-bearded owners and operators of Duck Commander in West Monroe, La. Duck Commander hand-makes duck calls.The story is a rags-to-riches one.Phil Robertson, the patriarch of the family, started his duck-call business some 25 years ago. The avid outdoorsman was dissatisfied with the duck calls that were then available, so he made his own.He did about $8,000 in revenue his first year, but slowly built up the business over the next few decades, hiring a lot of relatives along the way.His son, Willie, took over the company and has grown it to a $45 million annual business - one that has made the Robertson family mighty wealthy.
