I found a yard which had a small arena close to stabling, I had three ponies including a yearling and when it was icy for six weeks, they were out twice a day, including a session of loose schooling.
I spent time on grooming etc, fortunately I had no work, it took up four hours per day in two shifts. Most of the winter they were out during the day.
Most of the horses in the yard just got stabled or a bit of turnout while the boxes got mucked out, not much fun for horse or teenage owner.
Its not easy to own a horse.
