Ways to get some oils and flax seed in his diet?
My horse is boarded at a farm where he is turned out 24/7, and he is fed hay in the winter and grass in the summer with the occasional round bale (he has enough food, don't worry, he's a fatty xD). He doesn't get any grain, and I don't plan on giving him any.
I'd really like to get some oils and flax seed in him for his coat (we show throughout the summer), but without giving him grain (I don't want to buy my own bag, and the barn owner would charge me for hers), I'm not too sure how.
Are there any treats I could give him, or a mix of something I could make?
