My American Warmblood colt digs to China everything I feed him. I fill it back in daily. I can't feed him anywhere else. On the ground he spreads in, he dumps buckets...if I hang a bucket he paws it until he eventually gets his foot stuck in the bucket(which by the way he thinks is a game..no he doesnt panic) I've put mats down,he digs them out. I've put him in a clay foundation stall,he digs holes in my expensive clay. This horse is trouble.He CLIMBS my gaits(like a goat), gets into my tackroom(yes,turns the nob and opens the door. I have to put child proof nob covers...WHICH HE CHEWS OFF). I can't tie him to anything.He stands there are unties himself and any horses around him. I have double haltered him and triple tied him. He just works each rope until he is free. Anyhow I've become adjusted to those things but Im tired of filling the grand canyon in daily. Its like a 4ft hole when he's done!
