Economy Poultry farming The poultry farming industry in Gainesville began to develop after World War II, when Jesse Jewell, a Gainesville feed salesman, began his business. The format he developed was to sell North Georgia farmers baby chicks and feed on credit. When the chicks were grown, Jewell would buy back the adult chickens (broilers) at a price that would cover his costs and guarantee farmers a profit. Once Jewell signed on enough farmers to produce broilers for him, he invested in his own processing plant and hatchery. As of 2013, poultry farming remains a significant economic driver in Gainesville, representing six of its top ten employers (7,600 employees), nearly one-quarter of the total population in the city in 2010 (and a higher proportion of the working-age population). It is the most well-known business in the area, with statewide revenue exceeding $3 billion. These jobs have attracted numerous Hispanic workers, adding to the diversity of families in the city and county. The proportion of Hispanic and Latino residents is more than 40 percent of the city's population, where the jobs are.
