Abstract: An egg incubation carriage for a ventilated incubation enclosure, the carriage (10) having egg-receiving cradles (11) which are superposed in columns (13), said carriage including a plurality of juxtaposed columns, and the cradles of each column being tiltable in one direction or the other in alternation while remaining parallel with each other. The cradles in two adjacent columns are hinged to a common vertical riser (21), with the various risers being pivotally connected at their ends to a series of tiltable crossbars (29) which are pivotally connected to one another in series so as to form an assembly which is articulated at each link point of the crossbars to risers, and at each link point of the risers to cradles, with adjacent risers being capable of being displaced in alternation in opposite directions while remaining parallel to one another so as to fold up and spread out the articulated assembly, thereby tilting the cradles, with the cradles tilting in opposite directions in adjacent columns.

Abstract: A fan assembly (10) for an egg incubator enclosure (1) or for a hatching enclosure, in which a centrifugal fan establishes a pressure reduction and thereby sets up a flow of air through egg storage boxes disposed in the vicinity of the fan, wherein the centrifugal fan comprises two turbines (20) mounted on a horizontal axis and disposed substantially in the middle of the enclosure, with the boxes (2) placed on either side of the turbines, and with each turbine being constituted by a ring (21) which is hollow in the center and provided with blades (22) around its periphery. Advantageously, fresh air and recycled air are air-conditioned by being humidified (42), and heated (30) or cooled (41, 51) as required, in the central zone (11) lying between the two spaced-apart central rings of the two turbines, prior to coming into contact with the eggs to be incubated.
