So I started providing Crayon with a big 50lb red salt/mineral block again. She went through the first one in about a month, then a 5lb Himalayan rock salt in less than a week, and another 50lb block in about a month and a half. When she has free choice salt she drinks 40-50 gallons of water a day and of course kees a lot. I've been buying so much extra bedding, but of course I'm more concerned about what's best for heeled than what's convenient for me. I asked the vet about it. He even did a blood test last year to make sure nothing was wrong. He said it just goes right through some horses... So she just ran out of salt and I'm wondering, would you keep providing free choice? I have been taught to always provide free choice salt, but horses generally get enough salt from concentrated feeds or in grass, etc?
