I have a barred plymouth rock about 7 months old who was laying about one egg a day and just stopped. No molting, no broodiness, no eggs for the last month. She doesn't seem to be sick and our other 3 chickens of the same age are still producing just under one a day each. Any guess as to why?
Unless you are providing additional light, its likely just due to the shorter days. Chickens need 14-16 hours of daylight to keep in lay, generally.
I thought lack of light would just slow things down rather than cause a sudden stop in the egg laying of one chicken. The others are still laying like normal while the one hasn't laid in over a month.
Consider your other girls generous... Lack of light will affect them as well... It is good to give them a little rest.... Next year make sure you hoard a bunch prior to days becoming shorter...
