I have 6 runner ducks. They are 9 or 10 weeks old. I STILL can't figure out who is who. I know I do have 1 girl because she is a nonstop quacker. She started quacking early. She seems to do the talking for the rest of them. It's as if they are afraid to speak up. I'm really hoping that I don't have 5 boys and 1 girl. I have absoultely no luck with straight run. For instance: all straight run now........ 12 EE's and I got 11 roos and 1 hen. 8 French Black Copper Marans, I got 6 roos and 2 hens. I am soooo hoping this hasn't happened with the ducks too. We sold all the EE roos. Kept 1 girl and 1 boy. Eventually gave away the boy because he became to aggressive and the girl died at 14 months. No reason. We culled 5 of the Marans. I wouldn't know what to do if I got 5 boys and only 1 girl with the ducks. Here is a picture. It's not great but maybe someone can help me out. My ducks do quack but they aren't very loud They are molting again. They are getting darker.
