Since I bought chocolate wyandottes I wanted to make breeding coop/pen so nothing could get them so this is how its made I used 6 4x8 osb boards 4 whole boards then two half boards for the doors and another half boards for the divider I used about 16-20 2x3x8 for the bracers to hold it all together
