My 10 hens are 20 weeks old. Based on the research I've done, it looks like lighting is suggested to kickstart my girls' production. I'm fine with that, but the coop is a good 1/4 acre from the nearest electric outlet and my two young labs just LOVE chewing on extension cords. Suggestions on a light & timer setup that doesn't require an electrical outlet? Solar would glow all night, and I think that would be too much, right?
