They are not loud at all... I can't here them unless I go right next to their aviary. The wood ducks make a whistling sound and mandarin drakes make a sound that is hard to describe. I was planning on making a nest box page with pictures on my site today, but I just realized I have to upgrade to...
Are they agressive?
Not at all, but the males get a little more territorial during breeding season.
how big are they?
A little smaller than a call duck.
Do they really take 2 yrs to reach maturity?
Most will mate and hatch eggs their first spring.
how big of a breeding pen do I need?
You can...
