We have run outdoor extension cords to our coop - winter, rain, without a problem.I would like to put them in one of the old coops I have but there’s no outlet to plug the heat lamp in and they’re not as high elevated as the porch is. And maybe the porch may be like a chicken coop itself. And also, the porch is the only outdoor place with an outlet and it’s connected to the house which is also highly elevated. But with the predators, I haven’t seen any evidence left behind from them.
