Ok so I have a thoroughbred that is very skinny like supper skinny. Currently he is on 9 flakes of grass/alfalfa 4 1/2 qurts of oats and 1lb of horse charge. No idea what to do. I don't want to feed him to much because as it is I feel like that's crazy amount. I am going to try worming him. I totally forgot about the jan. Worming: oops:. But ever since we got him back in augist he has been skinny. We started at 6 flakes and 3 qurts but then increased it to 9 flakes 4 1/2 qurts and 1lb of horse charge. Any ideas??
