We moved into my wife's grandparents place. He had many sheds on the property. We converted the old pool shed into a coop. We built an outside run and have been making the inside better each week! The best thing is the shed comes with electricity!
The building of the run is basically easy although I still had help from family!
Inside we just used a devider to separate their food and supplies from the pen. Recently we added a roost. Next up are some nesting boxes!
