I was going to make this http://www.pvcplans.com/pvc-pastured-poultry-pen.htm But Lowes did not carry some of the connectors like the 3-way, 4-way, and 5-way. I designed my own chicken playpen based on what Lowes does carry. Here are pictures of what I just made. Hubby is supposed to help me add the chicken wire to it tonight. One side has a elevated bar so I can A-frame a tarp over it for shade and shelter. Lowes did not have 4-way corners. But Lowes has contractor size bags of T's and elbows at a discounted rate so I used them. Here is a close-up of how that corner looks.
