Q: I’d like to add a garden of ferns and flowers on the roof of my chicken coop, to provide some decoration and provide insulation for the chickens. What’s the best way to make the garden roof?
A: The roof must be sloped for drainage if a garden is to be located on top. The construction also must be adequate to support the additional weight. If the chicken coop meets these conditions, you can construct a basic raised garden bed on the roof by fastening a 2×4 lip around the perimeter of the roof. Drill holes through the lip’s lower edge. Secure copper tubing inside the holes to assist with drainage. Use a pond liner to waterproof the whole thing.
