Now that the nights are sometimes near the freezing mark, I have been closing the door on the coop. My girls are on the roost at sunset, around 6pm. I let them out about 6am at first light. I don't have water or food in the coop and this seems a long time for them to be without. When I let them out of the morning I throw out some scratch that they begin to eat, but they don't immediately run for water. I change the water with fresh that is just above tap temp but that doesn't encourage them to drink either. I let them out in the yard for at least an hour every day to eat grass and bugs. We have 4 barred rocks and they just started to lay Monday week ago. We got 5 eggs for the week and 3 so far this week. A penny for your thoughts.
