You all talk about using timers for your lighting for egg laying. Please explain to me how this works. My coop has a regular in the ceiling light bulb outlet that has a light bulb screwed into it so i am wondering how does a timer work with that? Or is that the wrong set up to have. I am thinking i will have to go out in the am and/or pm to keep it on for a couple hours if i plan to use what i have. thanks.
