How do I tell males from females in ducks? And how quickly can you figure this out if your a freshman to raising ducks.
With ducks, the noises they make distinguish males from females. Females make the loud quacking sound, while males make a froggy, raspy noise. With my runners, they all started out peeping as ducklings, then the quacks developed first (around 4-7 weeks old) while the males continued peeping for a while longer until they finally got their male voice.
Also with my runners, the males are quite larger than the females as adults. When they were ducklings, the alpha male grew to be bigger than the others as well around 3 weeks old (before any other signs of sex).
Finally, coloring can also signal male or female. WIth my fawn and white runners, the males have more brown feathers that are darker than the females.
I think there is a whole thread on sexing ducks (in the sticky section of the ducks forum).
Edit: Woops, I forgot to mention the sex feather. Males will eventually get a tail feather that curls up towards their lower back. I am still waiting for this in my drakes (4 months old), i expect to see it within the next month.
