I have never used shade cloth but need to do something to make my coop cooler. My coop is covered with a very large tarp. its 22 x 40'. It use to come down the sides like a building but I have opened it up and made make shift windows (cut out tarp) for my pens that are elevated. I put up guttering to keep the rain from coming in and can close this up with plastic for winter. My concern now is its all light now (had been kind of dark) but with that the sun makes heat. So I had gotten the idea to hang shade cloth on the sides. That way I still would have light and less heat. As I was looking at it (did not know it came in degrees of uv filtering) I have choices and don't know which to get. I want the pen to have the light it long needed and has now but reduce the suns heat. I had planned on getting the black but now worried it will make it dark. I could get white that reflects heat but White will soon become ratty looking. Heck I can not even wear white due to getting dirty so easy. lol Any suggestion on color or degree of filtering. As I have no clue. Thanks cj p.s. I have a friend that would give me black so that is why I have the question on if it will make it too dark.
