I have been keeping photo records of my DH progress on our chicken pens.
The only materials purchased were GOOD wood screws and nails, and ONE hundred foot roll of 1/4" hardware cloth.
One friend called it townhouses, another penthouses, but a DGer here appropriately named them the Coop-D-ville... five pens, about 36 square foot each, three with indoor access.... all from recycled and scrap materials.
take a peek...
