Where I board, the horses are all paddocked 1-2 per paddock (the single horses are surrounded by fenceline friends), and none of the paddocks are larger than an acre. Elle and her beau are in the largest one, and it's lots of space for them. There's also a nice slope to the property, so I have to say, the drainage is great. Which definitely helps. But the paddocks are poo-picked about once a week, and always look pretty pristine, even when they're due for it. They have netted hay in a raised covered feeder, but also graze the paddock all summer. The grass alone wouldn't be enough, so I'm glad they have both.
