A few days ago, he got the horse to put one foot on it and eventually eat some grain off of it. Now for the past week, he's been folding the tarp up until it's about 2' by 2' then he's puts the folded up tarp in the stall with the gelding and puts his grain on the tarp. The gelding is still very afraid of the tarp, and will only eat a few bites of his grain at a time and then goes to cower in the corner for a while. He does this every day, twice a day, with no improvement.
To me, it's sounds like the boy is just trying beat around the bush and try to quickly get the gelding to get over being afraid of the tarp. I suggested that he quit putting the tarp in his stall, and forget about the tarp for a while. I told him just to ride him, groom him, and just mess with him/let him get used to you. The boy JUST bought this gelding, so I told him that the gelding doesn't really trust him yet. I didn't get a straight answer out of the boy, but I really think he should drop the stall idea. What do you think?
