My first project with no building skills just a hammer and materials.
Started out with a base made from pallet's 5'x5'.
All materials were scraps from varous places, including shingles and vinal siding. Its amazing what people will give you if you ask.
My co-worker donated the sky lights and old bathroom window. We mounted window sideways and made it open from the out side.
Frame is 2x2 boards and osb for sides and roof. The house is 5'x5'x4'. Inside painted and calked, and cheap dollar store vinal on the floor.
Nesting boxis just inside door and its 12x12 has two compartments. The run was made from old dog kennel.
Total cost of purchased materials including chickens $125.00
