The last week or so my horse's poop has looked really broken down after it has sat for a couple of hours. The only thing that has changed is I got him a slat lick. I noticed that he has stopped licking his mineral block once I got him a salt lick though. Currently he is on approximately 2 and a half flakes of hay (they are really heavy flakes) 3 cups of Omolene 100, 5 oz of flax seed, a scoop of bug check, and a 1/4 cup canola oil. Is he missing something in his diet or maybe getting too much of something?
