We have thirty laying hens and one rooster. We have that many to try to guarantee eggs through the winter when even with a light on them, production goes way down. Last year, we did not get eggs from some time in October until late December. I'll admit, it seemed a little unfair to be feeding all those chickens and getting no eggs. The problem was they all molted at pretty much the same time.
This year, I also noticed a dip in production in September, just about the time I agreed to use eggs for a barter. Still, we kept getting enough eggs, and I watched the flock to see what was going on. It was pretty obvious that three or four chickens were molting. A few weeks later, we suddenly got closer to two dozen eggs again. In under a week, we were getting only five and another batch of hens showed signs of molting. And so it has gone the whole fall. Now, I think the last few have almost finished getting feathers and we should go back to close to two dozen eggs a day.
