I am new to raising backyard chickens and I'm in the process of finishing up my chicken run. I have heard both sides of the story through research and some say they need direct sunlight and some say indirect will be fine. I want to cover my run with metal roofing to prevent predators like hawks and stuff. I live in Florida where the sun gets hot in the Summer, so I was thinking the metal roofing would add shade for the chickens also. Will the chickens still be productive without direct sunlight?
