The Big Duck has been around as long as I remember. It was originally further down the road from where it is now but it's still on Flanders Road. It was built in 1931 to sell ducks and duck eggs. A baking note, I loved using duck eggs. I worked with a girl who had ducks and use to bring me eggs whenever I wanted to bake. It was a win-win deal. I would bake cookies and cakes and would make extra for her and we all enjoyed every bite.
The building is 18 feet wide, 30 feet long, and 20 feet tall. The eyes are made from Ford Model T tail lights and the interior space is 11 feet by 15 feet. The designed is the shape of a Peking Duck.
Long Island, especially around the east end had many duck farms. They are long gone, farms now McMansions. More information on The Big Duck.
