I first want to say that
I agree with the others.
Next, is your mallard is a male if he has a green head. The Aflac duck you are talking about is probably a Pekin(g). Can you post some pictures for me if the Pekins tail, feet, head and bill? This way we can make sure you have two males before you go getting more ducks and most turning out male. It’s always good to make sure
Next, like I said, I agree with the others. Usually, the rule of thumb for drakes is at *least* 2 females per male, like
@Roo5 said.
You can buy or make a duck coop. They sell them at
TSC and other farm stores usually. But remember that one duck needs 15 square feet minimum.
Drakes are known to mate with chickens— although please know that there is NO such thing as a chuck(chicken duck). When the male ducks (drakes) mate with a chicken, they don’t give you chucks, instead, they give you dead chickens.
Good luck!! Keep us posted please.
