I'd sure like to hear form someone with experience with laying ducks. I have 3 Campbells and 2 Cayugas who are 23 wks old. I've gotten 1 egg almost every day for the last 2 wks, but just one. It's a campbell laying, I can almost always see the egg bump on her belly the night before. They are getting good quality layer feed, oyster shell, veggie snack and some free range. What age should they all be laying? The Cayugas got bigger faster and seemed to mature earlier, but no sign of eggs from them. One has a black beak, the others beak is greenish. No sign of a drake feather on the tails so I'm not sure if ones a drake or not.
