I am planning for my first hens. I have been looking at coop designs and have a question about runs. It seems some are fully covered with a roof, and others have wire tops. I live in mid-Missouri, where it is hot in the summer and cold in the winter, and plan to place my coop/run where it will be mostly shaded by a large oak tree. I like the look of a full roof, but I am wondering if the hens will get enough sun in that situation. I also plan to use a mobile run several days a week, when I can put them on grass or garden beds, both of which will be primarily sunny.
