I built this 4 years ago.
Its till standing a little worse for wear.
I recently moved it and attached it to the run.
I used a couple pallets for the base/frame and laid 1/4" plywood for
the floor and walls and roof.
It also served as a brooder this picture was 4 years ago. Wish I still had those
chickens, Cuckoo Morans, sadly lot most to predators.
