DH and I were initially going to place the coop on the side of the house (its about 8' wide, fence to house) and build a self contained run using a 2x4 frame. After more research, and realizing how extremely NON existent predators are where we live- middle of the city, nothing more than an occasional stray cat (and I mean that, I'm a rehabilitation biologist for the city). That being said, we were hoping to just install a chain link gate/fence to the back portion of the side yard and leaving them the whole area to range free. To keep the roaming kitties out, what would we be able to use as a "roofing" material? We get very little rain, and dont need a solid roof (as their coop will provide them with a covered area). Can we just run chicken wire over the top? Anyone else have any experience doing this?? We would have redwood slat fencing on 2 sides, and the side of the house on the other. Only a 8' section of chain link fence/gate would be at the front... Thoughts??
