This 2 Hole Nesting Box is made with galvanized steel that provides durability and long lasting. The roll-back design ensures that the eggs roll away from the hen and into a collection area, which helps keep the eggs clean, prevents them from being broken and safe from predators. The floor of each compartment is slightly sloped towards the back, allowing the eggs to roll away from the hens to a collection tray or compartment. Adequate ventilation is provided to ensure a comfortable laying environment for the hens. Easy to mount to Coops or our Rugged Ranch Welded Pen
