I'm thinking about raising laying chickens. I got several books from the library. And be surfacing the net for guidance. I'm more confused. I live on the nw side of Tucson. And I looked in the law. I don't have much room but along side one wall of fence is free of neighbors but is total of 35' from fence to our brick house. Is this lawful to place a medium coop for maybe 4 hens? I'm thinking a narrow long double Decker kind.
