My babies are 6wks old now and I heard Winnies 1sr quake so I think I have A GIRL!!!!! But I think Roxy is a drake, no distinct colors yet but Mama Shorty is trying to be part of the pact with daily walks. NOW, my question I am going to build a duck house/run so what are the necessary things a duck run/hse needs?? I see chicken coops have to be off the grown so do ducks need that also? I have a bunny hutch to start the housing area and a want a walk in, I also have 2 dog houses, what do you use for flooring?
