Does anyone use solar lights for the inside of their coops? I just picked up a set of 50 xmas lights (solar) for about $10. I hung them so they stayed in a bundle over the nesting boxes and so far they are doing very nicely. It is brighter by the boxes and gives off a dim light throughout the coop and darker the roost. It is also a way to provide light but no heat. The lights are lasting about 8 hours (at this point, until about 2am). Anyone else do this? I would love any other solar ideas so I don't have to run cords out to the back.
