Last year we did this, as we had just got the chickens around this time of year and they completely stopped laying on moving for 6 weeks until artificially lit
We found putting the light on in the morning was best, adjusting the time to keep to at least 12 hours of 'daylight' depending on when the sun set. This way, as sunset arrived, they went to bed naturally, as we weren't usually home at sunset to put them away, and if given artificial light til later they wouldn't roost properly.
Haven't yet done it this year, but are getting paltry amounts of eggs, although almost everyone is moulting so this may settle once they've moulted, and there should be some reaching POL.
