I agree as well on the training for both yourself & your horse.
If he isn't cut already, do it pronto. Bad manners will only escalate & if he is still intact they will escalate at a faster pace. Cutting him won't solve his behavioral issues but it will make working through them a lot easier.
Take him out of the stall. Put the food in the stall then put him back in it. You might want to lead him with a stud chain. You don't have to use it but its there just in case. My horse is the lazyest boy ever but when its feeding time he get excited I lead him in with a stud chain. He learned real quick not to act a fool
Well, I took his mother to a trail ride this weekend to the bounty hunter trail ride in wilson nc. My son sayed , that he was kick and try to bite him.he kick a board down out of the stall. When I feed him ,he jump around like he don't have any sense
