I was tired of wasting so much hay feeding on rubber mats and if I placed the hay in tubs the girls would just knock it out. I purchased two nibble nets, the 9 inch width with two inch holes. The horses loved them and I wasn't wasting any hay. The horses are kept busy and don't gobble up they hay as fast! I loved then so much I purchased the 12 inch width with 1/2 inch openings. Love these bags more! We have one eye hook in the wall, the staps hang through that at the top. We found securing the bottom with eye hooks and attaching the bag with double ended snaps keeps the bag secure without using a strap on the bottom. We hang them with the bottom slightly above the chest. Our mares have no difficulty eating from them and I have found hanging the this way has been safe! I open the top while it is hanging, put the hay in, snap and they can enjoy. These are not cheap, but the initial cost has been well worth it. Saving money with no hay waste.
