Dark Horse Tavern » Horse has started eating stool?

hello,

One of my geldings are started to eat his own stool. He gets grain and supplements but only eats alfalfa hay wise. It’s a fairly recent thing, he started doing it 2 weeks ago. What’s interesting is that he only eats his own and not interested in other horses. I’m assuming this means he’s deficient in something. Anyone have experience in this area?

Please help.
Thanks!

I didn't find the right solution from the Internet.
