Just back from the stall. The grate had settled at least 2 inches. Since this morning feed, it would equal maybe 2 pads in 7 hrs. No hay on the ground. Stall is hay free. Now I know where the hay is going. When we put him up, he went to his food bucket which was empty, then straight to the box and started nibbling on the Bermuda that was sticking up. He had already eaten what Alfalfa that was there from the morning. I think he thinks he is grazing from the ground. As far as eating the grate, from what I've seen, when the hay is sticking up, he grabs the top and rips it, just like grass in the field. I did see him go to far and grab the grate with his teeth but let go when he realized something was not right. Have 2 strips of wood on each side to keep him from pulling the grate out. I am still testing pulling it up thru the grates making it look like grass standing. When it is completely eaten down, he uses his lips to pick it. You Tube "slow hay feeders". Best description is the videos. The one thing I am 100% assured of is since Friday morning he has eaten at least 1/2 of a bale of Bermuda that he would not have touched in a hay rack.
Another BIG thing I am starting to noticed. No racetrack around a 16x12 stall. Was the racetrack caused by boredom? Did not cut it tonight. Tomorrow morning will tell if he is acquiring a taste for the Bermuda.
