I had given up on trace mineral blocks with my 3 1/2 gelding. I put a couple in his stall, wouldn't touch them, I broke them up into a couple big pieces and put them in his grain bucket, then he wouldn't eat his grain. I finally just put two in his stall on the walls and he didn't touch them ever. Anyway, today at the new barn I put up his wall holder and a mineral block and while the farrier was doing my other horses feet what do I see?? He is licking it!! Unbelieveable!! Anyway, what a shock....my farrier probably thought I was a little nuts to be so happy he was licking it.
