There are several designs on this thread for some really great designs for building a coop for your birds. However, for those that want to be able to have the plans in front of them for reference or for future building projects I have compiled a list of books that have given me ideas on how and what to do in building my own coops and lofts. For those looking for historical plans for those old timey coops and barns. Barns of Yesteryear, Naturegraph Publishers American Country Building Design, rediscovered 19th century farmhouses, cottages, landscapes, barns, carriage houses and outbuildings. By Donald J. Berg, Sterling Publishers. Handy Farm Devices and How to Make Them, By Rolfe Cobleigh, Skyhorse Publishers For more modern plans: Chicken Coops, 45 Building Plans for Housing Your Flock, By Judy Hangman, Storey Publishing Practical Farm Buildings, a Text and Handbook, By James S. Boyd, Interstate Publishing How to Build Small Barns and Outbuildings, By Monte Burch, Storey Communications Barns and Outbuildings and How To Build Them, By Byron D. Halstead Barns and Backbuildings, complete with sources for Building Plans, Books, Timber frames, Kits, Hardware, By Donald J. Berg, (No publisher listed, probably Storey Pubs.) I hope this helps, I was able to borrow most of these titles from my local library, and a couple of them I have purchased for my own library.
