how many drakes?

[Chicken0Boy]

How many Mandarin drakes do I need for 5 mandarin hens?
Also can some one tell me how much space I need for thier duck pen, run type thing, and swimming room?
Can't you tell I am new at duck, but I am very excited!
Oh, and is thier any way of sexing them at an early age? If so about when can you sex em'?

Heres a link to a thread started by a member who has just finished making some housing for his ducks. Just thought it might give you some ideas.
