My hens are fine now, but I'm worried that later in the year, it might get to cold for them and they will need extra heating. My coop doesn't have any heat source in it and the coop is too far away from the house to run any electricity out to, I'm also having a problem with managing how much light they receive to try to keep them laying through winter. I considered solar powered lights but was worried about leaving them on all night and was wondering if there were solar powered lights with a timer. To sum it up I'm looking for ways to keep my chickens warm this winter and to provide them with light that they need to lay without running any electrical cords to the coop so maybe something solar or battery powered. Anyone have any suggestions?
