how long does it take for them to mature once hatched?
How can i sex them/when can i sex them?
are they loud or do they just hiss?
35 day incubation period.
They mature more slowly than mallard derived breeds - 5 + months?
By 7 or 8 weeks the drakes will be considerably larger than the ducks.
They hiss, and ducks will trill quietly - not noisy at all.
They are a great duck for eating.
