Hunting is more than a way of life for the Duck Dynasty clan -- it's their livelihood.
Willie Robertson is getting historical with his new book, American Hunter, which chronicles the true stories about how legendary hunters like Daniel Boone, Davy Crockett, Kit Carson, Buffalo Bill, Teddy Roosevelt, Ernest Hemingway, Lyndon Johnson, and more, shaped America.
"We went back and went through hundreds of years of America and really how hunting and the outdoors shaped a lot of the things that we see and do today," Willie tells ETonline. "We talk about presidents that hunted, all the way back to Native Americans. It's just fascinating... They're the ultimate conservationists, setting it up for future generations."
Willie's wife, Korie Robertson, even lends her voice to the book, recounting the story of her first kill. "I actually think he cried when I killed my first deer," she teases Willie. His response: "I did, yeah. I cry at everything. ... I was proud."
But Korie's not alone when it comes to female hunters.
"The most growing population of hunters in America is women," says Willie.
"It's really an incredible experience, it's something that you never forget," Korie chimes in. "You feel very powerful to be able to provide for your family in that way."
The Robertsons have long been champions of the (now trendy) farm to table movement, always cooking what they kill.
"We're looking for the freshest ingredients and we don't want something that's been pumped up with steroids, and you buy something from the supermarket -- let's be honest, you have no idea where that came from and what they put in it to preserve it," says Willie. "When I'm out in the woods, I'm able to see exactly what I'm gonna eat and I know it hasn't been shot up with anything. We clean it, which is another process, and then the cooking for us has always been a process, we love that part of it.
"And then as you see on Duck Dynasty, it's the meal," he continues. "That's where we share another process of it. It's the ultimate farm to table. ... We've done that our whole lives."
Willie and Korie have another new book out now, Strong & Kind, about how they raised their five children. The couple gets candid about discipline, and adapting their parenting styles to fit each child, in the video below.
