I have about a dozen layers. They range from Black Australorps, Buffs, Reds, EE's, Wellies, Golden Laced, and Barred rocks. We have used an incandescent rope light above the roost that is on a timer and it worked great last winter. We are in Central PA. We had 8 eggs and the next day we had zero. I looked all over the coop, the run, everywhere and nothing. The next morning as I got the kids ready for school, I noticed that the timer in the coop hadn't flipped the lights on. Come to find out that the timer had died. I immediately turned on the lights and then went and replaced the timer that very same day.
I have now been without eggs for over a week but I don't see an signs of a hard molt or anything. How long will it be until they start laying again? I'm not used to this and I miss having my eggs supplied every day! We save a lot of money on cereal and milk and of course it's better for my family to have eggs for breakfast.
They are getting a minimum of 14 hours of sunlight a day, with the exception of 2, maybe 3 days that the timer was out.
