When we moved to Texas last year, we had to leave our chickens and back yard chicken coop behind. After we purchased our home, two of the first tasks on our list were replacing our chickens and building a new coop. I used the same design, as my first coop, with a few improvements. The new coop is anchored in the ground using 4x4s and concrete. I also installed a metal roof since our area is prone to hail storms. The coop is made from 2x4s, plywood and T1-11 siding. Every joint was drilled and screwed with my cordless 18 V Ryobi ONE+ drill and driver, respectively. I also use my Ryobi cordless circular saw to make a number of the cuts. This is a great project for anyone looking for a back yard chicken coop.
