I live in No. Fl and have an opened pen for my ducks. It has a roof on it for the rain. The ducks free range all day and are put into their pen at night for saftey. I want to protect them from the winter winds, (winter is fairly mild here). Do you think a 50 gal Storage Bin WITHOUT the lid, placed on it's side, will work as a wind breaker? They would be able to go in and out when ever they want. I would put an indoor-outdoor carpet so they don't slip and also put hay in it. It would be easy to remove for the warmer weather. The bin is close to 4ft long and almost 3ft high and about 18' deep. I would get 2 of them. The plastic would be very easy to keep clean. Do you think this would work?
