My horses are in and out at their leisure. Right now, caring for them takes about 10 min. a day as they are on pasture. When the bugs are bad I'll spend another 10-15 min and stuff a few small mesh hay nets when they wish to stay inside. My quad pulls an old box spring (from a bed) to scatter manure which does away with the odor and dries to powder. This takes about 20 min. weekly. You can't be there all the time and the horse needs enough room to outrun dogs that may decide to give chase. Horses being herd animals need a companion, another horse, (a mini) even a goat.
