Commercial Housing System for Layers

Correct Answer: Both deep litter and cage system

For layer housing, both the Deep Litter System and the Cage (Battery) System are used commercially.

• Deep litter system: Floor space 3.5–4 sq. ft. per bird; litter depth 8–12 inches. Suitable for both layers and broilers.
• Cage/Battery system: The most intensive system; used only for layers (not broilers). Provides 14×16 inches floor space per bird with 17 inch height.

The cage system is preferred in large-scale commercial layer farms for its better egg hygiene, ease of management, and higher stocking density.
