I do mine all wrong according to some people.. I leave the light on 24 hours per daylkjWhat time does everyone set they're timer to run the supplemental light in winter to help egg production?
If you are going to just have the light on to extend the day, then you will have to readjust it as the days get shorter..
I would just figure out what time the shortest day gets dark.. then set the timer to go on a half hour before dark for that day.. that should cover all the days you need extra light ..
I think it is best to add the light at the end of the day instead of at the beginning ..
the main reason would be that the light will invite the chickens into the coop when it starts to get dark outside ..
