That's for your horses, looks like. Good for you. Don't be surprised if they inhale it. When horses are shut up they get really bored and when they find the mineral...BINGO!! This doesn't have much salt as a limiter. Can you put out some salt with it?
Yeah, 50# seemed like nothing when we were young, now its like UGH!!

Mr FH used to use a cart and a ramp when delivering mineral. 10 bags on a little pallet.
He was in really good shape then. Now it comes on a big pallet which holds 40 bags (1 ton)
so he no longer has to do that. The drawback is that when people weren't home, he could still deliver it, but now they have to be home or leave a bobcat out for the driver to unload.
