I bought clear poly tarps. They aren't actually 100% clear. They're more of a hazy, semi-transparent white but they let in a LOT of light. I bought one to fit each of my run walls and attach them with bungee and ball tarp fasteners that I feed through screw eyes that are screwed into the run frame. There is a 6 inch gap around the top where the eaves are open at the rafters that is left open. Each wall has its own tarp so I can just roll them up from the bottom to open up any wall I want. Most times I open the front wall because that is the one that faces the house and lets me see the birds the best. It is also the one that faces my prevailing winds though, so sometimes I roll it down from the top so air can get in but it is up high, well above the birds so they don't get blasted by the breeze. With the gap at the eaves I didn't have any issues with condensation on the inside of the tarps and air quality was always good. When I stand in the run with all the tarps in place I can feel air coming in the front eaves and blowing out the back, but down near the ground the birds feathers don't even ruffle. The sunlight that comes through the tarp raises the temp in the run a couple of degrees higher than the temp outside. Because the run is sheltered from the wind, I can open the window of my coop that faces into the run for ventilation in the coop without worrying that wind or rain will blow in.
The tarps were more expensive than plastic construction sheeting that many people use to wrap their runs, but I can use the tarps year after year. I didn't mind the extra cost because I wanted to be able to roll them up on good weather days. I know that in southern New England we can have some weird warm spells (like this week's expected 60 degrees F) and I wanted to be able to take advantage of those days and open up the run to the fresh air and sun. I winterized the run in early November when the weather was still nice. All the tarps were hung and then rolled up out of the way. It took me all of 20 minutes and most of that time was spent trying to remember where I had stored the tarps. As the weather got colder and we began to have more windy days I just lowered the tarps one by one.
I love my tarps. They are very durable, easy to install and remove, and are able to be raised and lowered as needed. The time and worry they have saved me was definitely worth the extra cost.
Where did you get your tarps?
