My design is a 12" flat top A-frame that allows you to have useable space all the way to the top.
At about 75 degrees vertical instead of 90 degrees, the bottom pen is useable all the way to the edge of the wire.
Bottom footprint is 4' X 8'.
I have 78" of roosting length, 16 square feet on the second level,
32 square feet on the ground floor, and three nesting boxes at least 12" X 12".
Tractor height is about 5 feet 5 inches high.
If I add a 8' x 4' x 3' wire run connected to it I will have 64 square feet of ground area.
I will have a dropping board under the roost to allow removal and cleaning from the end opposite the nesting boxes.
The botton of the entire wire meshed second level can be covered with boards or linoleum during the winter to keep them warm.
I have a 1 inch gap at the top under the roof line to aid in ventilation during the summer.
Understand that no chickens have actually inhabited this structure yet, but the structure is sound and I think it looks good on paper. I have assembled this with screws so I can revise and adapt as needed.
Six 3 week olds are going outside to their new home Saturday. They will let me know what I need to change.
8 standards might be cramped in this I think. I'm hoping my six will fit.
