My wife one day out of the blue decides she wanted chickens, which means that I was put in charge of building them a cozy little coop. I asked her to at least let me know kinda what she wanted and after searching through the medium coops on the site here, she decided se wanted something like this one by Hcarlsonlewis but with board and batten siding ... What did I get myself into That write-up was all I had to work off of. The only difference is we needed ours to be moveable so I modified the design somewhat to work on a base with 4x4 runners and made the coop a little bigger (6'x8') Let me just say that I am not an architect or even a carpenter, but I was able to come up with a design that somewhat resembles that coop with the exception of a covered run. Almost nothing in my design is on 16" or 24" centers, I just put studs where ever I needed them. For example, on the side with the next boxes, I spaced them at about 14.5" to end up with 13" for each nest box opening. On the walls with the window, I centered the window on the wall and split the difference on the other studs. Anyways, just wanted to let people know why I didn't bother to standardize anything. I did make the base 8' long so I wouldn't have to cut the plywood down in two directions, and I made the framing of the coop 3" narrower in each direction so that the wall girts will be out to the same dimension as the base and the board and batten can cover the walls and the floor base. Here is the plan that I drew up in AutoCAD before starting. It's not 100% complete because I haven't come up with a good design for the nesting boxes. I can update it here as I make changes. I was going to upload the CAD file, but it says I don't have the right privledges.. must need to be some kind of premiere chicken coop member.. LOL As I said, I'm not an architect and in no way guarantee the design... In fact I don't even have it all the built, I only have the base complete and the four walls framed up.. This weekend I should be able to get the walls stood up and the rafters in place.
