I guess my girls have stopped production for the fall moult. I have their light coming on at 4 am and staying on till 10 am, and then coming on again at 4 pm and going off again at 10 pm. Should they start up again in a month or two? They haven't layed since we had the broody hen sitting on eggs, and the results are a week old now. Oh, they are all buff orpingtons. They will eventually have a light on all night long when it gets colder (to keep the water from freezing).
