We built one. I found the plans for free off the net somewhere...I'll see if I can backtrack it later (trying to get us out of the house). But there were a few issues with the plans. One is the way the bottom was designed, there was a large crack where the bottom meets the side, and stuff falls out (and why hubby didn't figure that out and do something about it, I do not know...). There also ended up being large cracks on the end. I don't mind, as it is extra ventilation, but I worried during the winter about drafts. It's too heavy for one person to move, so our A frame is now stationary. We never put hardware cloth around the bottom as a result, since our chickens free range 100% of the time. My bantam Cochins live in that coop.
It ended up being an expensive build though.... the ends alone take 1 sheet of plywood. The floor was another sheet. Each side was a sheet. The scraps aren't big enough to use in another part of the coop, if that makes sense. I kind of think it doesn't save money to build coops unless you have free wood, after having built 4 coops now.
ETA: I canNOT find the plans we used! It was a PDF file that I downloaded from somewhere and have since deleted from my iPad. I'll keep poking, but it would be later. It's bigger than the one you would get from the free plans at Ana White. I will also post a photo of what we built. I never did get around to if sighing the paint job on it, so it looks pretty rustic.
