Is there a type of timer that can be used by plugging into a wall outlet so that it works with lights that are hard wired and controlled by a wall switch? There is not a way to plug the lights directly into the timer, but I have wall outlets to plug the timer into. This coop was already on the property and wired when we purchased it. I don't like having to turn it on at evening chores and having it on all night. I have to go to work at 3 am and don't get home till noon to turn them off. Not to mention the power bill which is bad enough in the winter.
