If you have a hoop run (PVC) is it very heavy? I'd like some sort of movable run extension so my chickens can get some fresh grass. I would move it maybe once a week and let the grass grow back, and then move it again. The problem is, it's windy and I'm scared if it'd blow away. We had a storm last night and I found the lid to my firepit in the driveway, along with 2 coolers. My metal trash can about 100 yards away, etc. I don't want to stake it down as it would be a PITA to unstake it every time I wanted to move it, however I want it light enough for a couple people to move alone. I'm thinking maybe 8'x8'.
