I have light in my coop for my convienece, so I can turn it on when I need to do things after dark or at dusk. I don't turn it on regularly for egg production, but have nothing against doing so if someone wants to or thier egg production drops that low. If I were going to do it, I would definately do it at night and not in the morning. Both chickens and roos are noisy and I would not want them to be making more noise earlier. I live in town, but even if not I wouldn't want the extra noise (I am not a morning person)I know we've heard the pro/con debate of lighting 1000 times, but have a lighting question for those that are pro supplemental lighting. I posted this in the egg laying/behavior forum, but maybe you all can chime in too.
I know supplemental lighting should be added in the morning so no one is caught off the roost, but is it really that bad to add it in the evening? I don't leave food in the coop and the birds never hang out in there. If I add the light in the morning, they'd be stuck in there for an hour or two until we get up (more of an issue in late winter when it would be going on at 4:15). In the evening would allow them to be in or out. It also may bear mentioning that I have solar lights in the run and a porch light nearby, so they wouldn't be plunged into total darkness.
