I have been artificially lighting my ducks in their house for almost 3 weeks. They are also given layer mash. They free range during the day and are in at night. The light turns on at 3:30 AM and off at 9:45 PM. What is going wrong?? They are all happy and everything. I added the light all at once, could that be a problem? I have Anconas. I really want them to start laying. 2 drakes 12 hens. PLEASE RESPOND!!!!
