My BO chickens are now 21 weeks old. They have been on a layer feed since they were 18 weeks old. We built the nesting boxes based on dimension and number recommendations for our size bird, added fake eggs, and allow our girls to free range for an hour each day under our strict supervision. They all appear quite happy and healthy. However, no eggs yet. Now that we are well into fall, daylight is shorter and evenings in the 30’s. So, should we not expect eggs until next spring? I have mixed feelings about using light to force winter egg production.
