I recently saw where you can cut 55 gal. plastic barrels in half and set on the ground for shelter for ducks. Anybody here done this or any tips on other quick n' easy shelters? Do you think they would be adequate for winter shelters in cold areas if you partially covered the opening and put some straw on the ground? I'm maining thinking about using them for my breeding pens in the summer for shade and a place for the girls to lay their eggs but I have some extra ducks I will be needing to keep outside this winter because my 2 waterfowl buildings are to capacity.
