A sprinkler controller in a poultry house having a processor, a data storage device operatively connected to the processor, the data storage device having instructions for programming the processor, and an input/output module operatively connected to the processor. The input/output module is configured to communicate with at least one valve for controlling a flow of fluid between a fluid source and at least one sprinkler nozzle. The at least one valve has an open position permitting the flow of fluid, and a closed position inhibiting the flow of fluid, and the position of the valve being determined by the processor. The processor is programmed to set the valve in the open position at a start of an activity promotion interval, and to set the valve in the closed position at the end of the activity promotion interval. The duration of the activity promotion interval is selected such that a sufficient amount of fluid is dispersed through the sprinkler nozzle to promote physical activity in the poultry. The start of the activity promotion interval is predetermined based on a frequency of operation parameter indicative of a number of activity promotion intervals in a time period, and a value for the frequency of operation parameter being selected to promote growth of the poultry.
