The invention relates to a battery cage for poultry farming, having the following features: - at least two horizontal cage rows (11； 11.1, 11.2, 11.3), formed with cage enclosures (12.1, 12.2, 12.3), are arranged alongside one another； - a plurality of the cage enclosures (12.1, 12.2, 12.3) are formed with double cages (13-13) made up of cages (13) that back on to one another in pairs； - under each of the cage rows (11； 11.1, 11.2, 11.3) there extends a droppings receptacle (20), over which air-compartment flaps (32) are arranged in a longitudinally spaced-apart manner, said air-compartment flaps (32) each having an upper force-transmission part (146) and a lower compartment part (147) and each being mounted on a transverse axis (33) that is arranged in the region of an upper air-compartment-flap end (54) of the particular air-compartment flap (32)； - the air-compartment flaps (32) are assigned pivot drives, which have drive rods (37； 37.1, 37.2, 37.3) that are drivable back and forth, extend in the longitudinal direction through the battery cage (10) at a distance from the transverse axes (33) and act on the air-compartment flaps (32)； - the two cages (13) of each double cage (13-13) have cage bottoms (16) that extend away from one another in a transverse direction (27)； - the two cages (13) of each double cage (13-13) are separated from one another in each case by a common vertical longitudinal rear wall (26) that is arranged at a vertical spacing above the upper air-flap end (54)； - the compartment part (147) of the air-compartment flap (32) is arranged under the cage bottoms (16) of the cages (13) of the associated double cage (13-13)； - the air-compartment-flap end (54) is arranged in a double-cage area (55), from which the cage bottoms (16) extend away from one another in the transverse direction (27).
