Hi - I’m new to raising and caring for ducks, and this website has helped me SO much over the past 7 weeks. Thank you!! However, despite all the info here, I still can’t figure out the genders of three of my ducks based on the sounds they make. One of them — a buff drake — I got from Metzer. The two Pekins and the Indian Runner I got from a feed store and have not been sexed. I think I’m tone deaf — can anyone tell from this video if any of them are hens? Thank you! The Pekins are seven weeks old and the runner is eight weeks.
