With this terrible New England weather I would like to report that my EE's started to lay in the begining of December. Their coop is not insulated or heated. I have no lights. The two of the four that started, lay every day to every other day. One tan egg and one blue. The only thing that I have provided is a well desined coop IMO and a heated water dish. So glad that I went this route for my first winter. Now I know they will be just fine!
