I’m just wondering if males mature faster than females? I have one male khaki Campbell, 5 female khaki Campbells, and 2 female Pekin currently in my run. My male duck Kenny has been mounting them for around 2-3 weeks now. I assumed when that started happening I would see eggs but I haven’t gotten any yet. They are all around 17 weeks old. We got them March 12th estimated to be about a day old.
