If you don’t have a beanfield to hunt in September, try to find one. They’re the surest early-season food source out there. “Shedding the summer coat and growing the winter one requires even more protein and energy than developing antlers,” says Dr. James Kroll. “When you start seeing deer’s coats go from red to gray, you know they’re seeking out protein. Soybeans are about 34 percent digestible protein, and that’s why deer swarm to them early in the season.” If you don’t have soybeans in your area, look for other green, high-protein chow. Alfalfa fields and clover plots are a reliable second and third option. But if soy grows in your area, find a field now.
