The PVC Pastured Poultry pen can house up to 30 turkeys or 90 Broilers. Allows them to rest easily, move freely and stay in a comfortable environment. It uses 1" X 1" wire and water ballast can be easily added through corner plugs to resist wind. The cover flaps can be opened for venting on hot days and are made out of two layers of 10 OZ., high density polyethylene for superior strength. PVC is high impact and rigid enough to support necessary equipment but flexible enough to fit ground contours. PVC pipe is 1 1/4" diameter. PVC piping and cover flaps have UV inhibitors. Pens are shippable via UPS. Assebly is required and you will need PVC cleaner and glue.
