I have 4 muscovy ducklings that are 5 weeks old. I live in upstate NY (pretty much canada). I have never built anything before and im attempting to build a duck house so any advice is appreciated! I have a 16'X16' barn that I am building inside of. How should I go about ventilating? Any recommendations for materials to cover the flooring inside? Any newbie advice about my set up? My neighbors are all amish so if all else fails one of their little boys will build it for me XD.
