Abstract: An in-ovo egg injection machine has a transversely or laterally movable supporting structure which is mounted beneath and adjacent the injector assembly and enables the operator to move egg trays into and out of the injection area from the side of the machine. The supporting structure includes two longitudinally extending opposed support rails that are mounted on a movable member so that the longitudinal support rails are spaced from one another at a set distance to define a support cradle. The movable member is supported on two transversely extending guide rails that are approximately twice the width of the injection area in length so as to allow the support cradle to be moved, preferably by hand, to an injection position directly under the injector assembly and then, by moving the support cradle in a lateral direction on the guide rails, to a loading/unloading position horizontally spaced from the injection area.

Abstract: A chicken or fowl grow out facility utilizes a ventilated floor assembly including a ventilated floor through which liquid and gas can flow, but which retains manure and other solids deposited thereon, and a bottom floor plenum underneath the ventilated floor. A liquid and vapor barrier sheet preferably covers the ground surface underneath the floor assembly which together insulate the high temperature of the grow-out facility from the heat sink effect of the lower temperature ground. Conventional tunnel ventilation of the chicken house through the ends of the house creates a negative pressure inside the house relative to the outside environment which is vented to the floor assembly plenum. As a result of this tunnel ventilation and negative pressure, moisture in the manure from urine and otherwise evaporates into the air in the growth chamber and floor assembly plenum to effectively keep dry the manure retained on the floor and reduce ammonia formation and pathogen growth.
