I put a little timer on a light in my chickenhouse, to go on at 6 a.m. (doesn't get light here till 7) and then come on at 5 p.m. till 9 p.m. So they should have 15 hours of light. Also have a little 15 watt bulb going all the time, so they can find their way to the roost when the light goes off at 9 p.m. They don't pay any attention at all to it. If I check on them at 8 p.m., for instance, they are all contentedly roosting with the light on. If they roost anyway, does the light still do any good? Mine molted, but are pretty well growing back their feathers now, so I think it is time they get going again. Getting about 5 eggs from 20 hens. All are layer types. ??
