I've had remarkably good luck with our little EEs. While all of the pullets in their first spring lay like crazy, it has been the EEs that time and again bounce back after the winter molt and resume laying at only a slightly slower rate. When the flock starts to get above three years old on the average, we do see a bigger drop in egg production. And no older hen will ever match the production that she had during her first laying season. But we have a 6-year-old EE that still gives us four or five eggs a week, and her daughter does the same. Our other older hens, like the Sussex, are not laying as well as that, but they're putting in the effort. I have to wonder if that "hybrid vigor" of the EE is part of the reason they lay so well.
That fall/winter molt hammers our girls every time, even the good layers: they're so busy growing feathers that by the time they're done, it's cold and the days are short, so they take a vacation. I figure that taking a break from the egg production is good for them, and allows them to rebuild their reserves for the next laying season. But I will try adding more protein to their ration this fall, and see if that helps speed the molt up: they range, but there aren't too many bugs out there in winter so maybe they've been deprived.
