I am new to this form and read more then post. I thought I would share my build with anyone who may be interested. It is an 8' X 8' and 4' from floor to ceiling and is mobile on skids 2' off the ground. It will house 13 large chickens with (6) 16" X 16" nests. There will be an 18" X 4' brooder pen with a 16" X 18" nest in one corner. Also there is a 2' X 2.5' storage/feed room. It will have (3) 8' roosts and to many other little details. Here are a few starting pics. As I continue the build, I will update with pics.
