We're going to be putting our chickens in our back yard. I have plenty of 10x10x6 chain link dog kennel panels available of the run but I was wondering how big it would need to be so that the ground underneath doesn't turn to dirt? I have 7 chicks coming and the coop will be 4x6 not including the nest boxes (so I guess that adds another foot to the exterior dimensions)... do you think we should do a 10x10, 10x20 or 20x20 run? The will probably be in the run most of the time since they'll be sharing the yard with our Irish Wolfhound... he's very gentle but also very large and clumsy so I'm not sure how he'll do with the chickens. My DH is concerned with the look of our yard so he really doesn't want the grass to be eaten up and only dirt left. Any recommendations?
