3riverschick, 21 hens-incharge and Nube,
Wow. Thank you so much for all that help. It gives me a lot of ideas I can use. The panel system looks promising. In that one link, I was surprised to see that they installed their panels horizontally. I suppose that helps if you want to use different wire for the bottom than for the top.
And Babs' warning about how wind can make a parachute effect on solid roofs has given me something to think about. I already knew I had to take a heavy snow load into consideration, but I hadn't thought about it catching the wind.
Don't worry, I'm not really planning to move this. But if we ever move (to my dream farm, sigh), I would probably want to either take it down and move it with us, or else sell it to someone else who would take it away. So I kind of think I need to make it with a level bottom, and not contour it to the ground. If contoured, it could only fit on a site with the same slope. But then my son told me that if you dismantled it to move and rebuild it, you could easily peel the wire up, cut the bottom of the posts even with each other, and rebuild it on a flat area.
But it is true that if I can make it "temporary", then I don't need a building permit. I have seen 4x4 post stakes that you can put into the ground instead of using cement, so I thought I might do that at the corners.
Babs, for some reason, your link only works if I right click on it and select "open". But I had to laugh when I read this part of it:
"We will provide the dimensions but after what you have done, we think you should be able to figure out how to construct the run."
I guess figuring it out myself is what it's going to come down to. But at least you guys have been a huge help with the details, information and links you have given. Once I get started, I will have to make a point to take photos and make a detailed article as I go along. Then maybe it can help someone else in the future. I decided I need to start with the pop doors, though. We've gotten our first snow, and it blew right into the open human door since I have that on the west side of the coop. If I can get the pop door made on the east side, then I can start leaving the bigger door shut all the time.
I noticed as I sifted through tons of threads on different coop builds, that some people include drawings in theirs. I'm getting kind of tired of sifting, though. Does anybody have any links handy to any more threads that have their design drawings posted in them? (That is, ones that include the run part.) If I'm going to sit down with some graph paper, then the more examples I have to copy, the better.
Thanks again, everyone!
