I have 8 ducks, 3 males, and 5 females (2 Cayuga females, a pair of Ancona, a pair of Welsh Harlequin, and a pair of Black Swedish), and my girls started laying a couple months ago. For the most part the eggs are chicken-sized, but I've gotten 3-5 a day every day for 2 weeks now. They seem to lay only in the two back corners of their house. They're free range, with a pond and lots and lots of pasture. I lock them up at night in a house approximately 2't x 8' x 8' with their food and water. I have 3 outside cats, but they honestly don't care about the ducks. They lay in the yard near the ducks and the ducks just go about their business without a care in the world. I also have a "cage" my hubby built when these guys were ducklings and we were first moving them outside. It's a wooden frame covered in chicken wire so they can't be eaten or get lost. I don't use it anymore though. So I'm wondering how I would go about getting them to hatch eggs? Do I need to wait till spring? Should I separate the boys and girls at night? Do they need a nesting box? What do I need to do to keep the ducklings safe?
