I had issues with our hens laying thru last winter, until we switched back over to our home made chicken feed. For awhile we were using pelleted feed from tsc or your local farm and barn store because no one wanted to brave the cold weather to mix up a new batch. Then we noticed there output dropped so low and a difference in the flavor of the eggs that we said what do we have to lose switching them back to home made mix. So I threw on my cold weather gear and made a batch. About 2 weeks later they stopped molting and started laying eggs like it was spring again in the middle of December in wisconsin.I may try that. Our hens egg production peaked last winter because we had fall chicks, but this year they are spring pullets. I don't know how well they'll lay through the winter. I'll find out I guess. Our few hens left from last year are moulting, looking awful and not laying. Except my faithful green egger, Paisley. She has laid and egg almost every day ever since she started. I'm definitely getting more Starlight green eggers next spring.
We had so many eggs out of 20 chickens from the beginning of december to christmas we gave 2 dozen of eggs to everyone for christmas. Plus we ate eggs and bacon for breakfast for every day in December until one of my kids said they need a change.
