I ran power to the back of my yard so my chicken waterer doesn't freeze during the winter. I also have a light bulb that comes on in the chicken coop during the days all winter long. It wouldn't be that much trouble to run an extension cord to my beehive and put a light bulb under the screened bottom board of my one and only hive. I know this concept won't be quite as feasible next year when I increase my hives to 4... and even less feasible the year after when my hive count will most likely increase yet again. I'm just wondering if there is an obvious problem that I'm not aware of or that I might be missing. My hive sits on two cinder blocks with no foliage within several feet of the hive.
If a light bulb is a problem, it could always be a heating pad or something. I'm just wondering if it would be worth the trouble.
