Our hens were laying up until the end of November was our last eggs we received then New Years Day came and they started laying. This is a strange year here since they never did this until this year. Usually some of them will molt but not all which happened. We have a 10x20 Palace which is their coop,laying boxes and where they roost at night. Our run area is larger than the coop, not sure of the size right now. I read too many treats, human food will cause them to not eat their feed. If they don't have a space without being crowded some hens will start pecking on other hens, this happened here. One of our hens is a pecker but she is doing better since the winter and now the bigger hens peck her back so she not doing it too much now. You don't want a pecker that is last thing you want. I would turn off your lights for the chickens since is almost spring now. Our worse month for cold this year was Jan.
