You have rather different climate conditions as I understand it and the chickens may have to spend time in their coop. It's everybody out here most days, even if it's not all at once.I bet they love that.
Nice. Mine is closer to a mini barn than a coop, but it could be moveable, if I rented several large forklifts.
The only times they are very reluctant to come out is when it's very windy. I used to think this was because they didn't like getting blown about. I think what the real problem is is they can't hear in high winds and that means they can't here warning calls, wing beats, the other animals who also give alarms etc.
