Okay, so I gave in and bought the "herd" some Himalayan salt licks. I bought the "baby" ones that come with a rope. I figured if they didn't lick them, maybe they would play with them, especially Quad, who seems fond of investigating things in his corral. Nope. The only one who has even touched theirs is Scout and I found hers flung out in the middle of her corral. She tried to eat the rope on hers, so we took the rope off. Does anybody use these things? Do your horses like them? Anyway, here's Cali investigating hers.
