The PolyDome Duck House is made of UV stabilized polyethylene. The house size is 10-3/4″ wide x 11-1/2″ deep x 19-3/4″ tall in the front and 24” tall at the back. There is a removable bottom for easy cleaning. The backing is wood for simple installation and is 28″ long. A wire mesh on the inside front helps young ducks escape when they are old enough.
