I won’t do supplemental lights I read it’s not really good for them it’s unnatural to force their laying so Id much rather let nature run it’s course. I have a light but it’s a nighttime bulb so it doesn’t give off light just for heat. They do need the heat they aren’t very winter hardy birds. My chicks were purchased in May!Completely normal, unless you are providing supplemental light. Hens shut down on the shorter light days of winter. It's good for their longevity, if that matters to you. I have 60+ hens this winter and in the last 4 weeks, we've been in the single digits. I added 7 hens in April, who are pretty much the only ones laying right now, and another 20 hens in September. They'll start laying in March. Basically, if you want winter eggs, get chicks in April/May. They won't be molting in September and will be more likely to lay in the short days of winter as it's their first season. Older hens will shut down, but, for me, I'm fine with that, because it means they will live and lay longer.
