Has anyone tried using a solar yard light in the side of there hen house to increase egg production? I have a chicken tractor\\ark with a small hen house 2'x3' and I am thinking of cutting a small hole in the top of the roof and slipping in one of those solar yard lights, but I don't know if they put out enough light. In winter with the days being shorter they should only last a few hours and in summer i can just remove the battery until next winter.
