My mother is wanting to buy a night light for our 4-5 week old chickens, we plan to have it stuck on one of the walls inside the coop. I see that the main reason for lighting is to encourage laying but my mother is really only concerned about them being able to see at night and "not being scared." Would it have to be red??? And here is our coop and chickens(we don't really know what exact breed they are). My dad built it and I helped him out, it exceeded my expectations! These aren't recent as we extended the run and we just put in roosting polls in today. So will a night light hurt them at all? And does it need to be red?
