VEVOR Chicken Nesting Boxes, 2 Compartments, Easy Egg Collection, Wall Mount, Easy to Assemble, Galvanized Steel and High-Strength Plastic, Roll Away Nesting Boxes for Chickens Laying Eggs, Orange

Yes. You can mount the nesting box on the outside of your coop, provided it is securely installed and protected from rain and harsh weather.

For this VEVOR roll‑away nesting box, the best materials are thin straw, pine shavings, hemp bedding, or plastic/astroturf nesting pads. Use a thin layer so eggs can roll freely to the collection area and avoid breakage. Do not use thick, bulky bedding that blocks eggs from rolling.
