Finding the Right Fit: Comparing NATURA® Layer Systems for Cage-Free Success
Upgrading your Cage-free performance to meet growing demand
August 25, 2025
As cage-free adoption continues to grow across the U.S., producers are faced with more choices than ever when it comes to housing systems. But not every barn or business requires the same layout or functionality. That’s why Big Dutchman offers multiple cage-free true aviary models under the NATURA® line, each designed to support flock welfare, optimize egg flow, and fit specific building designs.
All NATURA® systems feature an automatic tiltable nest floor that gently transfers eggs through the system with minimal movement. Each system is also designed with the proven “step” concept to prioritize easy movement between tiers and access to litter aisles. Strategically placed perches also provide comfort and encourage natural bird activity throughout the system.
Whether you’re retrofitting a converted barn or building a new complex, selecting the right system can streamline labor, reduce floor eggs, and improve overall performance. Here’s a quick look at four of our most trusted NATURA® models and how they stack up:
NATURA® Step & Step XL
Our most popular and versatile systems, the NATURA® Step & Step XL, are ideal for a wide range of house layouts. Birds move easily between tiers, and the open design makes it easy for system inspection and flock management.
- Compact footprint
- Unrestricted movement between tiers
- Customizable nest depths
- Low floor egg rates
- Excellent for retrofits and new builds
- Step XL offers up to 26% more usable space for larger flocks and improved comfort
- Step XL offers dual egg belts for higher egg capacity
NATURA® Visio
The newest addition to our NATURA® lineup, this innovative system is engineered for maximum visibility and smooth egg handling. With integrated ramps, alternating nests, and a low-profile structure, the Visio encourages bird movement while simplifying management.
- “Visio Twin Belt” design improves egg quality and inspection access
- System-laid eggs roll onto egg belts without passing through the nest for improved egg quality and cleanliness
- Nests alternate between both levels of the system but are aligned, creating more space in front of the nests
- Flexible layout with integrated ramps for narrow aisles
- Optimized for both performance and retrofit capabilities
NATURA® Nova Barn
Designed for barns that prioritize open movement and simplicity, Nova Barn offers a stepped, multi-tier layout with clearly defined zones for resting, feeding, and perching.
- Open access encourages natural activity
- Elevated walkways integrated into the system simplify daily inspections
- Nests are located on two different levels to allow hens immediate nest access on the lower level, while nests on the second level are offset for easy egg collection and nest inspection
- Higher stocking density to optimize the space in your barn
- Flexible design works well in diverse housing styles
