Our Coops are built with two triangular frames made of top quality 2" x 4" lumber. The 1" x 4" slats are attached with screws, not nails. Our Coops are available in 12", 18", 24", and 30" heights. They are painted inside and out with a primer and finish coat for long-lasting protection against moisture. Because the sides are open, they serve as built-in handles for easy moving. Coops are sold in pairs and are available in three lengths to fit beneath 8', 10', and 12' jumps. The base measurement of Coop is equal to the height measurement. They are available in white, stained or any standard solid color.
