I am in Washington and 2 out of my 3 six month old pullets have stopped laying. I am new to chickens and not sure if they start slowing down at this time of the year due to the shorter days. I thought it may have been later when the days are really short, right now we get about 12 hours of daylight. They are a Speckled Sussex and a Light Brahma that have stopped, the Light Brahma layed only one 2 weeks ago and never seen one from her since. The Speckled Sussex layed about 2 dozen before going on strike about the same time.
