Keeping Chickens laying in the winter
If you do these couple things they should lay all winter long. My Grandma taught me to do this, and she always had fresh eggs in the winter
Put a light in the coop we just hang on from the ceiling, it keeps it a little warmer and the chickens think the days are still long, then keep a light on the water that keeps it from freezing and keeps the water a little warmer .
One of my daughters did a science experiment on this one year and the chickens with the light and warm water did lay more eggs.
And don't forget the extra protien like meat scraps or fat. If you have old meat in the freezer that is freezer burnt that is a good use for it.
