I needed a way to give hay to my goats in the "hospital stall" but didn't want to spend money. So I took one of the new style of feed bags that are woven plastic strips, cut three diamonds across the front and back towards the bottom, put holes to run baling twine through at the top. I fill them with hay, run the baling twine through, and hang on the fence. So far they seem very safe because the holes aren't big enough to get their heads through and no one has torn them up. And....totally free!
