There doesn’t seem to be much of a slow season at Ferndale Market, but there’s most certainly a busy season. As Thanksgiving approaches, the feathers really fly. “It’s our time to make things happen,” said John Peterson, 37, who represents the third generation to raise turkeys his the family’s farm near Cannon Falls, Minn. John estimates they will sell about 30,000 fresh and frozen Thanksgiving turkeys this season, both straight off the farm and through retailers and restaurants across the Upper Midwest.The Peterson family has carved out a distinct niche for themselves among consumers seeking an alternative poultry product, raised on grass and without antibiotics and growth promotants.“They’re grateful that we’re doing it different,” John said. “Most consumers don’t really know where the frozen turkey in the grocery store came from and how it was raised.”People — hundreds of them a day in the weeks just before Thanksgiving — flock to the Petersons’ on-farm retail store, along U.S. Highway 52 between the Twin Cities and Rochester, Minn. They enjoy seeing exactly where their turkey was raised.
