I would say it depends on what is your situation. Are you at home during the day or gone? Do you have neighborhood dogs to protect your hens from? Are you near a highway, that might present a hazard if your hens got out? I guess what I'm saying is perform a threat assessment of sorts. Everyone will be different because of where we live presents different dangers. My yard has plastic bird netting over top because I work during the day and I left my chicks in the hen house yard while they were still small. I didn't want my mom to have to worry about hawks swooping down and flying off with my chicks when they were outside in the yard. The plastic won't last a long time but my hens are big enough now that I am not as worried about hawks. My house has a pop door and a drawbridge type ramp that folds up at night. So nothing can get into my pop door. All my windows have hardware cloth over them. We did put concrete around the fence and buried it about 6 inches under ground, just to deter my own dogs from digging under the fence. There is also concrete about 6 inches deep along the 6 foot wooden privacy fence that runs along the outer edge of the yard to deter neighborhood dogs. They could still get in if they are determined enough. Hope that helps. My pics are on my profile page. You can look if you are interested. I don't have a pic of the ramp yet.Thanks TXChicmum! I'd love to see pics of your setup. I thought about buying a shed from home depot but that wouldn't help me keep busy until I can actually have chics so I am going to try to stick build.
Question for anyone. I know the coop should be predator proof, does the run need to be as tight? Meaning does the wire need to be buried to prevent digging, etc? I see tractors often and I'm thinking that those can't be that tight so that maybe if the coop itself is tight the run can be less so?
