I checked Dr. Google on this and couldn't seem to find anything definitive.
I'm building this: http://learningstore.uwex.edu/Assets/pdfs/A3908-02.pdf
and it just has a hole for the coop entrance. I live in the Portland, Oregon area, so it gets to freezing a bit in the winter but nothing like the midwest. Do I need a door to close it up at night for temperature reasons? Is having a run door secure enough or am I going to be inviting predators if I don't close them up at night?
