I have a new girl that can fly pretty good, since she's at the bottom of the pecking order she keeps flying out of the run (which is covered but is poorly done since I did it myself). So I'm going to tarp it since it's nothing but mud and the snow should be coming soon. I tried a blue tarp we already had and it was so dark the girls didn't want to go out. What color tarp do you guys recommend? Do they make clear or white tarps? The run faces the East side so it gets a lot of morning light.
