I know there was alot of it baled here in Arkansas last year and sent to TX/OK. I had called our extension service to inquire and he advised against it (silica). Said he would rather buy rolled sage and supplement - my response was there may not be any sage hay!! I know a group from Texas cut over 1,000 rolls off my father-in-law's place last year. I just wanted a first-hand experience if someone had any. Thanks in advance!
