Kind of like people. Butler sees many lessons for humans in his birds. "It's relaxing to me the way they can just go fly freely and, regardless of where you take them, they can find their way home," he says. "So it is a learning experience. You say, 'Damn, if you take a bird somewhere and he never been there before and he will make his way home, and he is one of God's creatures, then why can't we just fly freely like a bird?' And they're just so humble," he adds, looking into the coop, which Stewart is now cleaning, a mask covering his face. "They don't hurt nobody. They just want to eat, poop, have sex, and fly. And that's it."
