basic 6x6 pen. Wanted them to be able to get on top of stuff and exercise. We build this with a wood 1x4 lumber frame supported by 2x2's. The cage is standard chicken wire. The door features a pin and hole enclosure, hinges and a coil quick return and makes access to feeding watering them easy. Temporarily it has a tarp roof with a 1x4 standing from ground to top keeping the tarp from falling on them.
