I have often wondered if hatch season makes a difference in the age a hen lays her first egg. Seems the heavier breeds generally take longer, but if winter light is at its lowest, and all else being unchanged (diet, health) the time to first egg may be delayed by several weeks. I wonder if adding new egg layers in Aug/Sept would result in more consistency.Born early spring heritage bantam breeds can start laying in the fall. I have a few who did so. One was laying through winter. But all the other pullets stopped during the shortest days.
Any thoughts on that?
