help with indian runner ducks/2 males 1 female

[weplant]

Hi..I am new to forum and to ducks..I have 3 indian runner ducks that are now 7 weeks old. I love them. We just built a run for them outside with a secure coop. Up till then they were in the house, what a mess.
My concern is that I think I have 2 males and one female..I am freaking out, because I love them all, what will happen..Thanks

Well, duck math says just get more females until your ratio is better Not much help if you can only house 3, I know.
