I added a light on a timer to my coop to deal with the fact that it gets dark awfully early. When days were long I was getting five eggs a day like clockwork. So, help an impatient person out: How long will it take (on average) to get the girls back into the "lots of light! Lots of eggs!" mode? A week? Longer? I have difficulty believing that the eggworks can be turned on or off very quickly but I could of course be wrong.
