I don't have to tell anyone here that chickens are addictive, and we recently decided "two flocks is better than one" and decided to build a second "reclaimed lumber" coop. It's almost exactly 3 years since we built our last coop, documented in Coop-struction: Reclaimed Lumber Coop (aka "crate expectations"). Like the previous coop, this one started with reclaimed lumber from window cases. The lumber and windows all came from a friend of the family who owns a custom window and door business (thus "crate expectations"). It starts with a base...I don't like bending to clean out the coop. After the last time we built a coop and then delivered it to my yard (realizing it weighed literally a ton), we build this one module and assembled in place. Here's the frame: The side panels, roof, and other components are built to be slapped in place and nailed in: Can you believe I got those windows for free? They're small "samples", but they're nicer quality windows than I have in my house. Lucky chickens!
