3 out of my 4 pullets are still laying. They are on a layer feed, 16% protein I believe but I will double check. I don't know if they will continue laying through the winter, but I'm wondering if I should keep them on the layer feed or switch them to something with less protein. The one that has stopped laying is a light brahma and they are a heavy breed not known for laying, but I'm not sure if she is too fat because she isn't laying and still consuming all that high protein feed. But maybe they need the extra protein for keeping warm through the winter, I don't know. Right now it doesn't get below 45 degrees at night.
