I have searched the archives for people using solar powered lights in their hen house. My coops range the pasture, so I would like to avoid dragging an extension cord hundreds of feet every week to the new location. Who has managed to rig a simple solar powered panel, battery, timer and light into their hen house? Is their an off-the-shelf product I can just goggle and buy, or is this going to be extreme electrical DIY? It's getting to the time of year where we all need to be thinking about supplemental lighting for our layers.
