The Hatfield family lives on the east side of the Hatatoochie River and the McCoy family lives on the west side. Each family's diet consists of fried chicken and corn on the cob, and each is self-sufficient, raising its own chickens and growing its own corn. Assume the Hatfield family has a comparative advantage in the production of corn. Assuming that each family is producing efficiently, how can the two families increase their consumption of both chicken and corn?
