I'm reading Horse Health and Nutrition for dummies and of course they say pasture is the best type of boarding.. but after that they say that paddock is best ( bigger the better) and then box stall. And they don't seem to rate a box stall with an outdoor enclosure as good as a paddock. I assumed box stall with outdoor enclousure was better than just a paddock. ( the combos I see are, of course, have smaller outdoor enclosures than the just plain paddock) How big should a paddock be? They say horses like to be outside and only a sick or recovering hourse would be good in a box stall.
