Many people forget that egg laying is connected to the length of day. So as days shorten they lay less eggs. In the old days, women 'water glassed' excess eggs in summer so they had eggs all or most of the winter. an old chicken breeder told me he used xmas lights. I thought it was a joke. then I tried it.
