"Nova Scotians, they're rednecks also," said Dwayne Doucette, a Canadian who was with the group holding signs that read: "We love Duck Dynasty" and "Canada loves Duck Dynasty and Duck Commander."
Jase Robertson, whose real name is Jason, said the duck calls are still handmade, one-by-one. To meet demand, the business has gone from a dozen employees before the show aired to about 75 in the past year. They make 14,000 duck calls a week, he said.
Fans buy the duck calls even though many have no intention of hunting, he said.
Casey Cambre and his 5-year-old daughter, Ava, waited more than eight hours to be the first in line to meet the family.
"I've never done anything like this, ever, not even for a concert," said Cambre. "A lot of people like the show because it's funny. I like it because it's a good, clean, wholesome family show."
Each of the show's episodes ends with the family gathered around the dinner table in prayer.
"We're trying to infuse a little good into the American culture," Phil Robertson said. "Love God, love your neighbor, hunt ducks. Raise your kids, make them behave, love them. I don't see the down side to that."
Si Robertson, who is always with a tall cup of tea in hand, said he drinks about two gallons of unsweetened tea a day. As he sipped some during an interview, he said it was a misconception that he drinks sweet tea. That would rot his teeth, and besides, he said, he's sweet enough as it is.
"I'm so sweet I can't get out in the rain. I'll melt," he said.
