Multi-tier open access aviary system

The name NATURA Step comes from the unique steps which are designed to allow easy movement from one tier to another. A multi-tiered system which is fully open, the NATURA Step provides full freedom to the bird to move in and out of the equipment at all times. All of our NATURA aviary layer systems share the same innovative COLONY2+ nest with the patented tiltable nest floor, resulting in a cleaner nest, higher percentage of nest acceptance, and fewer cracks and checked eggs.

Perches and Placement

There’s science in perch design and placement. Perches allow your flock to have a place to relax, and the design of the perches provide comfort. The placement of perches encourage flock movement which relaxes the flock, and at the same time maximizes proper air circulation, resulting in a healthy and comfortable environment.

The patented approach perch is designed to protect any mislaid eggs. It also positions the hens to face outside of the system while roosting, allowing the manure to fall onto the manure belt, resulting in lower ammonia levels and a cleaner system.

Easy Movement Vertically From One Tier to Another

The name NATURA Step comes from the unique steps, which are designed to allow easy movement from one tier to another. These steps are made with our Zn Alu wire coating, and are positioned so manure falls on the manure belt, resulting in a cleaner system.

Fresh Feed and Water

Fresh feed and water for the entire flock:


The entire flock has easy access to fresh feed and water whenever they want it. Our feed and water placement is intentional in order to promote bird movement within the system. Water is placed right outside the nests to provide the birds a drink after they lay their eggs.

Feed is strategically placed inside the system to promote bird movement and open up quality space.

Encouraging bird movement is vital for a healthy flock. When birds move around air flow is increased, resulting in healthier birds, a calm flock, and drier litter.

Nest and Egg Handling

Maximize egg laying and egg quality

It’s the hen’s natural desire to find the most secure place to lay her eggs. The nests are located in areas to provide this sense of security they seek. After the egg is laid, it gently rolls out onto the extra wide egg collection belt, and then heads to the egg packing area automatically.

Nest Acceptance 98%

The average nest acceptance is 98%, but for those rare times when an egg is laid outside of the nest, we’ve designed a built in system egg tray to allow picking up the mis-laid eggs easy and fast.
Operation of the tilting nest floor
(patent-no. EP 1 086 623 A2)

egg farm chicken house
The egg belt is located in the center to allow the eggs be laid directly in front of the belt . This design ensures the shortest possible roll-off distance for the eggs, minimizing the amount of cracked and checked eggs.
egg production tilt
Before the divided nest floor completely closes the nest, it is first raised in the center, increasing the inclination of the rear part of the nest floor and removing any eggs from the nest area.
egg farming
The nest floor is raised completely, allowing any dirt to drop off the nest insert as well as closing off the nest to prevent hens from entering and brooding inside.

Properly dried litter for a healthy and calm flock:

Uniformity of lighting and ventilation, along with system design, result in even spacing of the hens throughout the house, resulting in properly dried litter. This is ideal for the flock as they dust bathe, scratch, and act out other natural behaviors. The hens will pay more attention to the litter and less to each other, resulting in a calm and healthy flock.


Management made easy:

With our NATURA cage-free systems, flock inspection, gathering mislaid eggs, nest, feed and water inspection can all be done by walking the litter aisles.

Waste management:

Proper manure drying reduces ammonia emissions in the house, minimizing any harm to the environment, and promoting the birds’ well-being. Manure drops through the Zn Alu coated floor onto continuous polypropylene belts, and is then carried out of the building.
