Companions for male muscovy

[Le Moth]

I simply want to know if it would be wrong for this guy to have his two sisters as companions?
I certainly wouldn't let any babies hatch, wouldn't even let the girls brood but I love his guy and at the moment he is in a pen beside the girls, all alone.
I don't want him to be on his own and we can't afford to feed anymore ducks than we currently have.

As much as the idea of them mating icks me out, a lot, would it be wrong or would it be okay?

He is gorgeous. Let them be together as long as you take up eggs they will be fine mating..

 

[chickens really]

Let him out with the girls. They will be fine.
