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. As a result, the cradles can be tilted alternately in opposite directions without splitting up the columns which would establish empty passages between adjacent columns and interfere with proper ventilation of the mass of eggs.
