I have decided for safety (we recently lost 4 pullets to predation) and my sanity to build a run for my chickens as they have completely killed every single blade of grass in my front yard. Now it's a packed-dirt poo landmine field. Yuck! So, now that they're all nice and cozy in their new enclosure, what will I need to do to neutralize the soil and which variety of grass would be appropriate to recover this area? I live in central NH, Zone 5-6 and the yard is partial shade. Any advice is welcome!
