Mine have free range all the time, except during breeding season where the Frizzles are confined to their run ( which is huge anyway because one doesn't get on with my others and harasses the non frizzles ). So they have their runs/ pens but they are open all the time otherwise. I find that the free range makes them happier, and they eat less pellets, mine didn't like the organic pellets that we tried them on, so I switched back to the original ones.
