10x12 coop with a 10x8 pen. Insulated. Unheated and unlit. 4 opening windows for light and ventilation. Pen wire is dug over a foot into the ground and reinforced with some other kind of strong wire. Metal roof. Roosts run along 2 walls all at the same height to prevent scrapping over a higher roost. 4 nesting boxes with slanted roofs to prevent roosting. Kindly built by my husband.
