DIY Plans are available online. I have had my coop for several years and the clean up is so easy! Plus I have never lost a chicken to a predator in this coop. I love looking at it from my kitchen window! Mine is the "Daisy" chicken coop.
The mesh walls and roof are secured with washers and screws spaced six inches apart along the studs. Bright red geraniums in the window box bloom almost year-round in the mild Northern California climate. Love the red screen door!
