I need a run and I'd like it to be covered so it will stay more dry and protect the hens a bit more during inclement weather. The run will be built along an existing fence on two sides, so it should only need 2 sides constructed and a gate to get inside. It will be approximately 20 feet long by 5 feet wide. I want to use the SunTuf polycarbonate for roofing [which has to be special ordered at my local Lowes...no one seems to carry this stuff in stock in Chicago.] I'm not handy, nor do I have tools or much spare time so I went the route of getting some quotes on the work. That didn't work out for me at all. No one seems willing to do the work as needed, unless they can incredibly over-engineer it. [I had one person tell me the job would require sinking 20 posts, because the roof would need support!!] So, it looks like I will have to wing this one myself. I'll have to take a week off of work (and soon since I have 3-week old chicks in my basement right now) and try to do this myself with borrowed tools and some female ingenuity. I don't *think* that a polycarbonate roof will need to have a lot of support. Am I wrong? Couldn't I just secure it to the top brace of the existing 6-foot fence and the top brace of the to-be-constructed run wall? If I don't run trusses (or whatever the heck they're called) will the roofing not be secure enough? Also, do I *have to* dig post holes for the new run wall? If I use a heavy 4X4 along the bottom and secure the wall posts to it is that enough? If I take this approach will my structure fall down in the next strong wind? I've seen structures on this board that don't look like they are constructed with posts sunk into the ground, so I'm hoping I can use that approach. The only real drawback I can think of with this approach is that the "sill" could rot quickly being in contact with the ground. So, I would first lay out and level concrete paver bricks (I have lots left over from another project) on the ground and actually have the "sill" on that. I'd also use cedar, which is rot resistant. Advice will be greatly appreciated. I'm pretty scared to do this on my own, but it doesn't seem like there is any other option at this point.
