I have a roof covered run and the coop is inside that, I will try to get a picture to upload. I’m planning to run the lights all the way around the top of the run on the inside. There are two coop windows which have awnings over them from before I got the run finished but I will be removing the awnings so more light can get in. I don’t plan to put lights inside the coop. The door open in the picture is the egg collection door so it will be closed. I will try to get better pictures of the windows laterhow far your Christmas lights going to be away from the coop and are the windows in the coop big enough to allow enough of light on top of their heads? Or are you talking about placing battery operated Christmas lights insider the coop?
