Hello, i have almost completed the construction of my chicken coop. One of the things i still need to install is an artificial light. The coop is about 40 foot away from my house and i need ideas of how to get electricity up there. What is the cheapest/best way? Also what type of lighting should i use and what wattage should i use? The coop is 8 by 8ft. Thanks for all your comments in advance, Luke.
