I started to raise Guineas this year along with a Blue Slate Turkey and a few French Copper Maran chickens. My attempts are free ranging Guineas didn't work too well. I decided to build a coop. This set up was built within a few months. I need to cover the roof then all will be done. The sun room, with the windows, faces the East. The material used were just setting around the farm. The cost was practically nothing.
