description: Reared in enriched rooms. Rooms had visual markers to help animals locate (colored markings on the walls, on the weighing chains, and feed hopper chains) and various enrichments (a two-level platform, fringes along the first level of the platform to create a dark space below, providing a sheltered area, four linear perches, five vertical dividers to structure the space and meet the need for gregarious resting and shelter, perforated dispensers for pecking, three foraging balls, one dust pan filled with wood dust, three pecking blocks (similar to the ones in C rooms), four straw bales (similar to the ones in C rooms), one 18 m² area with wood shavings )
