Last weekend I toured Hickory Hills Organic Farm with my Des Moines Paleo group. We saw all the animals and then got to buy straight from the source. The chickens, hogs and cows are treated very humanely. They are actually ranked between category 4 and 5 on the USDA's humane scale You can talk to Ben at the Des Moines Farmer's Market.  The roasts are perfect and the brats are the best I have ever had.
