With is starting to get colder here in Northern California (sometimes below 30 degrees) I have hooked up a heat light in the coop. Should I only have the light on a certain amount of time? (Darkness hours, morning to extend daylight hour?) I want to make sure that they can be comfortable and coninue to be productive in the they're laying. Anyone have any suggestions. I was thinking about getting a thermostatlly controlled outlet for the light and/water hook up for the coop.
