OTOH -- chickens are tropical birds. At the equator it's 12 hours of day and 12 night, more or less. So to me it makes sense to adjust their day to at least closer to 12 hours, not for eggs but to come closer to their natural cycles. Not sure I'd do it all at once at this point, though.
The other side roost by 4:30-5:00pm and are sleeping shortly there after.... as soon as all chicks have grown out enough I will shut those lights off for the Winter-
