So, winter is coming up. I have heard not to provide a heat lamp as the birds will acclimate to the cold weather. However, I also heard that it is good to provide a regular light 12-14 hours per day as the light in the day gets shorter because chickens need a certain amount of sunlight to lay through the winter. Has anyone had experience with this? Do your winter layers lay without an added light source, or should I think about running a light out to my coop? My coop is 8x6 and 11 feet high but doesn't have any windows. The only opening is the little door out the back that's large enough for a chicken to fit through so its fairly dark when closed. We are still planning on the windows (we got the coop on craigslist). I have pullets that all range from 5 months to 7 months, and are about to start laying. I hope to maximize my chances at getting eggs soon and through winter (at least a few per week) but don't want to do anything unnecessary or have them get accustomed to something they don't really need. Thanks.
