Greetings, duckish folks! I am in the process of building a 4 x 4' shed for my little sis, in the hope of her getting three ducks. Would it be better to put on a plywood floor and raise it on cement blocks like you'd do for chickens, or just put it on the ground on some sort of thin support? Can ducks sleep on the ground, albeit with a thick layer of bedding? I'm just afraid the walls of the house will rot. Any thoughts? It is only about 3' high with a slanted yet-to-be-put-on roof, FYI.
