Abstract: An aviary is provided having a floor and a first aviary cage including a first outside surface enclosing a first inside area. The aviary further comprises a second aviary cage substantially similar to the first aviary cage and including a second outside surface enclosing a second inside area. The second aviary cage is positioned at a height from the floor greater than a height from the floor at which the first aviary cage is positioned. An aisle extends between the first aviary cage and the second aviary cage. A first perch extends from the first outside surface of the first aviary cage and into the aisle at a first vertical distance from the floor. A second perch extends from the second outside surface of the second aviary cage and into the aisle at a second vertical distance from the floor. The first and second vertical distances from the floor are not equal.

Abstract: In existing cages for breeding hens and cocks, hens habitually gather at the four corners of the cage and lay eggs there. Experiences tell that feces produced by concentrated hens make it difficult to obtain good quality hatching eggs and many eggs are damaged and that hens who cannot get a relaxing position at any of the four corners miss chances for laying an egg. These two factors make it difficult to produce good quality hatching eggs. The present invention proposes a novel cage that is sanitary and efficient and can make hens who tend to gather at the four corners scatter.
