Many egg producers keep chickens in small cages that do not allow the chickens to move. some people believe that this is unhealthy, so they buy eggs from chickens that are not caged 24-hours a day. these are sometimes called “free-range” chickens. the united states department of agriculture (usda) allows chickens to be called free-range as long as the chickens spend some of their time outside. the european union (eu), however, has several additional restrictions. one of these is that the farmers must provide enough outside area so that if all the chickens were outside, the density of chickens would be no more than 0.25 chickens/sq meter. (wikipedia, 2014).
