Well..my friend's horse apparently did so this past weekend and it really freaked him out. He's never done it before, and he can't see the reason that he would.
He has the same feed/hay/minerals that he had before he moved them back to his house. Bale of Timothy/Mix second-cut hay per day, a 10oz scoop of (I believe) 12% sweet feed and a mineral block.
The only reason that I know of is lack of necessary minerals or malnutrition. Pistol hasn't lost any weight, still acts the same, etc. There's no reason he should be eating his own manure, from what both of us understand.
Before the vet is brought out for something that's happened only a few times, he wanted to get other opinions.
