Our 5 month olds are laying like crazy now, including Buffy, our Orp.
The lights in the barn come on at 7AM, after they already have the morning
sun in the window. The lights aren't shut down until 11:30PM. They get 17
hours of light.
I know some may say this is too much, but because of our schedule a lot
of my chicken time is in the late evening. I'll spend some quality time
with the chickens from 10 to 11 after all the chores are done and my kid
is in bed. I believe leaving the lights on is better than turning them on
after the chickens are already roosting.
I have 3 20 watt halogen, under cabinet style lights in the chickens coop
area. We also have a few flourescent lights in the barn itself.
