Yes, duck eggs are nice and rich. Great for desserts of all kinds.
WindyOaksYokes -- that's a tonge twister -- my ducks were about 20 weeks (5 months) old before they started to lay. It's always just about the time you start to wonder if they will lay at all that they finally get around to it.
Separate them so that the ducklings can't get through any little holes. One of my brave ducklings did just that and his father bopped him on the side of his head, before I could separate them. The poor little fellow walked around with a tilted head for months, but eventually grew out of it.
