My wife and I expanded the chicken run today. It is an additional 4x4. We took the plywood base off the old area that came with it. The whole run now sits on flagstone. The chickens seem to love it. They were free ranging in the yard while we assembled it and when I threw the hay in they ran right in to check it out. The old blue tarp and new cover should help with rain and snow and protect from predatory birds. Now to start on the new coop. It will be 4x6 and 6' tall with a pitch down to the left. Plywood floor with sheet vinyl cover. Two windows, south (right side towards run) and north (towards workshop). A walk-in door on this side and outside nesting boxes on the north side. I plan to install roosting bars on the east wall with a poop shelf with Sweet PDZ on it under that.
