coop designs for ducks?

[tadpole98]

I will be getting myself some call ducks this spring (and possibly mandarins once i learn a few things), and need to come up with a coop for them.
Heres the deal, i have a large shed i could convert into a coop, if that would work, or i could build my own. we have a five acre lake for them, or if they want smaller, we have a littler pond.
I just need to know some basics, size for ten ducks, roosts? laying boxes, ect.
Heres your chance to show off those coops!

Unless you clip their wings, Mandarin ducks need an enclosed aviary. They also all need access to water. We are currently building an aviary for our Mandarin and Wood Ducks so I don't have any photos right now.
