Most of my hens are 3 years plus. Some pushing 5 so I'm not surprised that the bulk aren't laying. Our winters here are pretty rough especially Dec, Jan and Feb.
I do have 6 bantam pullets and 3 EF pullets I hatched this past spring. They are laying but now full force. Getting maybe 10 eggs a week from the bantams and 3-4 from the EFs. When it turns colder they take the day off.
I've used lighting before. Usually they have natural light from the pop door and two windows. If it's really cloudy and rainy out I will plug in a light for them during normal daylight hours.
Years ago I got in the habit of saving eggs back starting in the fall. We eat eggs sporadically, mainly use them hardboiled or in cooking/baking. Right now I have about 4 dozen on hand which should hold me till February when they start laying again and the bantams are giving me enough fresh eggs for meals and the like. My girls stick around until they leave this realm of existence due to age or infirmity. I promised myself when I hatched this spring that I wouldn't hatch this year. I want to decrease my flock until I have only bantams and my Fayoumis. I'll see what 2023/24 brings before I decide whether or not to hatch more EFs in 24.
