I had set the timer in my chicken house to come on each morning at 4:00 in order to give the hens enough hours of light. Yesterday morning I looked out the window and it was still pitch black outside, but I could see the light on in the chicken house and the chickens moving around. I felt kinda bad because I went back to sleep and slept another couple hours. I decided that since chickens did well without artificial life for many centuries - they didn't need it now. So I turned off the timer. This morning they woke up when the sun rose and it was daylight - and for the first time in a very long time, every single hen of laying age laid an egg today - before lunchtime, too. Coincidence? My question: Does having the light on 14 hours a day really make that much of a difference in egg-laying?
