Abstract: Methods and systems provide for incubating a plurality of eggs at least partially at a primary incubation location and then incubating the plurality of eggs (e.g., a plurality of single sex eggs sorted from the plurality of eggs) at least partially during transport to a secondary location.

Abstract: The present invention comprises a method for cyclically controlling a poultry barn environment. It coordinates stimulation such as illumination, ventilation, sprinkling and temperature. At the commencement of the cycle, the lights are turned off, the ventilation is reduced to a normal rate and heaters are turned on to provide an optimum environment for the poultry's inactive phase. During the dark, inactive phase, a massive purge is implemented to reduce ambient dust. At the end of the dark phase, the lights are turned on, sprinklers are turned on and the temperature in the barn is reduced. The lights stimulate activity by the fowl. The sprinkling removes still more dust from the air.The reduction in temperature stimulates feeding. At the end of the illuminated, active phase, the lights are turned out and the cycle is repeated. By coordinating the stimulation, a healthier fowl and greater growth rate are thereby produced.

Abstract: A ridge ventilating device that allows for the passive ventilation of agricultural buildings and the like, and which device resists the affects of snow or ice and allows for regulation of the flow of air from the building. Pairs of hinged door panels which operate by opening and closing coincidentally with each other, thereby covering and uncovering an elongate ridge passage cut into the ridge or peak of the roof structure. The doors are hingedly attached along the outside edges of the passage so that they open away from each other and create an unobstructed opening in the roof for the air to exhaust through. Each door is pivotally attached to a connecting link which connecting links are in turn connected at a common pivot point to the shaft of a dual-acting air cylinder. The air cylinder thus provides the motion for opening and closing the doors.
