I wanted a very safe place for my little Seramas. DH & I put together this pen, covered sides and top with vinyl covered chicken wire. Bottom 2 ft of pen is 1/2 x 1/2 wire. The pen is 6 ft by 12 ft, and at the back of the pen is the 6 ft by 3 ft coop, up on legs so that the grass under it is also available for them to get to, and also under the coop is shade or protection from the rain, if they don't want to go inside the coop. On both ends of the coop, I have put a door that can be lifted for air flow in summer. Also the window in the front can be opened for air. All 3 openings have 1/2 inch hardware cloth over the openings. The back doors open for complete availability to clean. It is on skids so that it can be moved to fresh grass. Will try to put some pictures. The chain draped over the back in the last picture is the chain to move it with--stored with the coop so someone doesn't have it drug off and used for something else,when I need it. It is MY chain.
