Tim, is it as cold in NY as it is in California/Nevada? Very few of my birds are laying. I've discovered a lice problem and am dealing with that but it has been bitterly cold here. Several of my roosters have frostbite on their wattles, a few have it on their combs. I'm attributing the non-laying to the cold, so perhaps lights in your coop will help. I have several rooster pens and it would be very difficult for me to provide heat over each pen. Even some of our roosters that are in with the girls and therefore have extra warmth have problems!
