I am always out with them, and it was only 2 weeks since his blanket was last off. I didnt even think he looked that fat til everyone pointed it out. Then I took pics to sit back and look at. He has been on free choice rounds. He is now restricted back to a coarser cut, and is only getting 3 flakes 2 times per day. (about 12 lbs 2 times per day) I put it in a hay bag, and he still had some left when I fed him the next batch, so hes not gorging, I think that maybe it was just too high quality hay for him.
