It is 4 ft. by 8 ft. Made from 2 x 6s; 2 x 4s; 1/2" thick plywood sheathing, shingle roof, 12x12 floor tiles (they only cost us .05 cents each); it's wired inside for heat and lighting. We used hardware cloth for the windows and eaves vents and we purchased clear light fixture ceiling tiles (.99 cents each) so we could slide them in/over the windows and cover them in colder weather yet still let light in. We have a sliding egg door and are using milk crates for the nesting boxes. We have 3ft x 2ft barn doors at the other end so it opens wide for cleaning. The roosts are rounded off 2 x 4s, (they are removable too for cleaning) Final cost sans paint, $185.00. More pictures to follow.
