I am beating my brains out not knowing what my chickens like at night. Right now I have a wired pvc enclosure covered with a tarp so it is totally enclosed. Wind does manage to get in for ventilation.. I want to build an A-frame coop for the night (chicks roam my whole yard during the day) and don't know if I can have areas that are totally open at the ends, partially open or almost totally open. Are the chickens afraid if they can sense it isn't totally covered? What I am saying is, "Can I leave areas exposed to the night, covered by chicken wire and have happy chickens?"
