I have two Black Marans that were born some time in March. I thought they would never give me any eggs but then on Oct 21 they started to lay. I have had 14 eggs since Oct 21st. So they will lay in their own good time and each time I check the nest box I get excited. The decrease in light and the cold setting in does not seem much of a factor yet. So, for those of you that are still playing the waiting game, don't loose heart, it will happen!
