We have a large fenced in area that is not being used on our land. Thinking of building it up so they cant fly out and use as a run. Its the size of a pretty big urban back yard. I know people with short runs either have to rake or make it a tractor and move frequently. Anyway, I was curious how clean upup would go if I had them in a lalarge area/run like that. Would I still need to rake? Could I mow it and that scatter the poo good enough? First time chicken owner here, will be getting chicks soon. Also, if they have such a large area, could they be free range eating off the land or would they still need same amount of bagged food? Thanks!
