I am the happy owner of two horses (one Appaloosa mare and one Quarter Horse gelding) that live at home on our property. For those of us who only have a couple of horses to take care of, I wanted to share my tip for toting hay flakes. I use a laundry basket (the rectangular plastic kind with handles) to take hay flakes to the stalls and also out to the pasture. I find that it makes it easier to handle flakes and also cuts down on waste, as you don't lose half of the flake on the barn aisle floor or on the way out to the pasture.
Using a laundry basket also is a good way to "pre-measure" what you are going to feed in the morning. After my last barn check for the night, I go ahead and put the flakes in the basket for the morning feeding so all I have to do is take it out to the pasture the next morning. It's a lot less expensive than the hay totes you see at tack shops and also a good way to take extra hay when going to shows, trail rides, etc., when you don't need a whole bale.
