I've read so many posts about how chickens 'fluff up' the ground with all their scratching, but I've only ever seen hard packed, bare ground in chicken yards. So which is it? Does their scratching really help fluff up the dirt, or no? Mine are not old enough to be out in their yard yet and I am currently trying to decide whether I will need to section off areas of their yard (roughly 800 sq. ft. for 15 or so birds) for a period of time to help it recover and re-grow. I really hope to avoid having hard packed dirt in their yard.
