Yes, my 5 EE's are laying very well through the winter. I do supply extra light in their coop at night. Light is on a timer and goes on at 4 and off at 7:30. Two lay light blue, one is green and two lay pinkish eggs. However if you want to know if they lay in the nests, now that is another story, they are always finding some new out of the way place to lay their eggs! They are very shy.
