That looks like one of those movable chicken pen things. That's actually state of the art. You rotate them through the pasture so that there's always some lush pasture and some in various stages of having been decimated by the chickens. The pasture gets time to recuperate while the chickens are busy trampling another section. In exchange, the chickens get water, shade and protection from predators. There's probably supplemental feed in there, too. They always get supplemental feed no matter what.
