Chickens might be small animals, but they’re the backbone, wing, thigh and breast of a huge industry and a tight-knit community. Poultry professionals from around the world are gathering this week at the The International Production and Processing Expo in the Georgia World Congress Center in Atlanta. This year, the expo is an integration of three trade shows, including the International Poultry Expo, the International Meat Expo and the International Feed Expo.
