Although incomes from poultry houses are relatively predictable, cash flows fluctuate year to year as a result of changes in flock production factors and economic conditions. To demonstrate this fact, this report uses data collected between 1992 and 2002 to estimate and project cash flows for a 20-year period for a typical tunnel ventilated broiler house placed in operation in 1992. As with any cost and returns analysis, these estimates are not intended to be representative of all growers' situations. Growers may do better or worse than the projections here. These results are particularly helpful to individuals considering investment in new or existing production facilities, but they are also suitable for use by poultry integrators, lending institutions, students, agricultural appraisers and county agents.
