I usually buy them at my feed store. I may have to have them order them for me this year, though a Blue Seal that my hubby passes by during his hour commute has whole barley listed on their web site. I buy a 50# bag at a time, figure it will simply take the place of any scratch grains I might possibly buy. Given the quality of feed the grains produce when sprouted, I figure they are worth it, in spite of the initial up front $$$.
Thanks, B2R. That further confirms my decision to go with sprouts again. Thinking about buying a bag of wheat or barley, and a bag of BOSS.
