I have 6 pullets that are 4 months and 6 that are 3 momths. I intend to add light to their coop next month That will make 20 layers for the winter. Never had light in coop before.I've never added light to my coop, but I might have to try. I just need those pullets to start laying so I can make my decisions. I think think about feeding them all winter for zero eggs.
