I got welsh harlequins last spring, and at the right time, they started laying. 9 ducks, 9 eggs. As fall turned into winter, a few got broody and my production went down, 6-7 eggs a day. The trouble is that I had heat lamps on the waterer. So they had 24 hr a day light. Now they don't have the heat lamp on and I'm getting two eggs a day. I know I could force them into a moult with no lights, but it is springtime, so there is more natural light. I've got them on a timed light (about 15 hrs), but it doesn't seem to be helping. Any ideas?
