Here is a message directly from my mother: " At 3:23 pm on July 1st, Teresa has ridden her princess bike into Heaven to meet Jesus. She had her ears pierced shortly before her last breath. While we were not there when she took her first breath,God blessed us to be there when she took her last." -Ann
Why not start with an IBC and cut a hole for the door? You could build closed laying boxes into it, and something for the chickens to roost on. Put some straw or saw dust on the floor. You could add vents to the side for air. If it sat inside a chicken run that you can walk into, the chickens could be safe, dry and happy. I have an extra IBC. Maybe this could be my chicken house? I bet I could even plant the outside of it with mud and grass for extra insulation and good looks.
