I have a few red tailed hawks in the area that have never been a threat up until now. I tend to free range my birds but can no longer do that. I am looking to build some PVC pens with netting. That way they are lightweight and easy to move around for fresh pasture. Does anyone have any pics they can post of theirs? Or advice to building them? I'm not much of a carpenter, lol so this is all new to me!
