I have 2 pekin ducks. I bought them as day olds, and they're now 3mos 1wk old. Duckie, it's very obvious she's a female. Pekin, I'm pretty sure is a drake. Pekin is very loud all the time, and quacks very loudly. Pekin on the other hand is very quiet and has a low raspy sound. I've tried to get good video of it, and I've tried to see if I could find videos online to help, but I've not found much of anything. When I try to get video of them they decide that it's time to be quiet. They stare at my phone (my only source for recording video) and they're silent. Personality wise they're very different from each other. I've never been able to hold Duckie without her freaking out, scratching me, and making a lot of noise. Despite frequent handling. Pekin on the other hand, I could probably hold Pekin for an hour or more with very little protest (only when I'm not holding in a preferred/secure way will Pekin make a little noise). Pekin is a little big larger and heavier, and always has been. Very laid back. I've been trying for the last couple weeks to get a good sound clip of them, and I'm going to continue to try. Aside from the drake feather (which I'm reading mixed information on coming in later versus earlier), does anyone have a good sound clip of male versus female?
