An industrious spider built a web in front of the coop camera. Although it looks vertical in the picture, the actual web was horizontal, stretched from under the camera to the cable tie end shown in the picture. Unfortunately, when I rotated the camera, the web broke. I generally leave spiders alone in the coop. They provide valuable insect control, especially of the flying type, without toxic chemicals (unless you count the spider bite). The successful arachnids are in the upper part of the coop, since chickens are keen on devouring spiders. Extra protein. A few times a year I do sweep out the old webs that are full of dust to make room for new webs.
