I have two speckled sussex hens and one leghorn hen. As the days became shorter, they all molted and stopped laying. As a result, I recently added a light in the coop that runs from 6 pm to 6 am and as a result I have been consistently getting a white egg. However, the speckled sussex are not giving me eggs. Everything I have read indicates they are good winter layers but it doesnt appear to be my experience. They are all about 10 months old. Does anyone have any suggestions?
