Yes, I'm sure there is a moderate approach to artificial lighting. For example, you could make sure the daylight isn't less than 14 hours, OR anymore than that. Some that use the 16-18 hour schedule, to me, are asking for trouble. If you are a commercial operation, I'm sure you would choose the longer period, but then, they have to replace their layers about every 2 years, some do it every 3, I think. They dont care how long the hens lay after that, or if they caused any issues after the spent hens are disposed of. I'd rather they live a more natural life, overall. It's always your choice, I suppose. Hatchery stock is already chosen for their egglaying prowess, sometimes to the detriment of all else, and will continue to lay in winter, to a degree, anyway. I lost 3 hens this year who were all under two and a half, to internal laying, and I dont want to contribute to their early deaths in any way.
