I have 24 layers, 5 Cochins who lay when they feel like it, and 1 roo. I go through 4-5 50 lb bags of layer feed every month and I keep a bowl of oyster shell full that they can crunch free choice. I free range all day long on 10 acres, but in reality they probably only use about 2-3 acres. I don't feed scraps at all. I get right around 18 eggs per day, plus or minus a couple. I keep the light on til 9 pm, it comes on at 4:30 p.m. and off at 9 p.m., and they never miss a beat. They can be VERY tricky about finding places to hide eggs though, I've found them buried in the hay stack, in the hay feeders in the barn, under an upturned stock tank, you name there's no end to the creativity. My chicks will be 1 year old in Feb 2013, and they didn't really start laying consistently until late Sept or early Oct, so your youngsters could just be getting the internal stuff working right about now. If their wattles and combs are all bright read and if your yellow legged birds are still bright yellow, they probably haven't started laying yet. They'll start fading when they do.
