Hello! I have 7 girls that are almost 19 weeks now and although it still is relatively early I concerns over their egglaying. I have heard that in the winter I need to supply artificial light, so do I? To get them started? P.S. I was originally planning to let my chickens be natural in the winter and not supply any light. Secondly due to the proximity of my chicken coop in relation to my house, running electricity isn't a viable option so is there any other way to get electricity/light in the coop?
