I have a pair of Welsh Harlequins. The duck has given me an egg a day since Christmas. She hasn't missed a day. Eggs are fab for baking! The rest I sell to someone I work with. She feeds them to her show dog who has trouble maintaining weight and is a fussy eater; but she loves duck eggs! The ducks are worth having around just for the entertainment factor!I know. When I went to TSC and saw the bargains I had to call him. I knew he couldn't refuse. Did he tell you he might end up with ours anyway. Good guy! I do like the size that the Campbell's will grow to. Smaller duck and not much bigger than the leghorns. Maybe we will keep them. Hope so. I just don't like too much mess. Everything I have read about them says that they can lay up to 340 eggs a year. Now that's production!!
