Hay bags are important because they minimize hay loss due to wind, trampling and soiling by horses if fed on the ground. All you have to do is slip the hay pole over your t-post (see instructions), snap on the hay bag, and the horses will take it from there!
I offer a "gusseted" hay bag. The gusseted bags hold 3 mid-sized flakes and are incredibly easy to pack, snap shut, and cart off to the feed stations in your Paddock Paradise,
