Hi boys & girls... first post but have been reading here for a couple of months now. I'm about to finish my coop/run. It's a "Playhouse" type design. Will post pics when I'm done. It's been a lot more work than I thought. Anyhow, my question is: I live in Carlsbad, Ca. (One mile from the ocean) in north San Diego. It's pretty much 74 degrees here year round, 60's at night. Now it does drop into the 40's at night on a cold snap in the winter and it might hit the low 90's during a heat wave in the summer. Other than that, it pretty much 74 degrees. So..... is it necessary to put/confine chickens in the coop at night?? The coop/run is one unit and secure so predators are not an issue. TIA for any answers!
