Meanwhile, the female hasn't given up on the remaining eggs in her nest.
The other two ducks are keeping their distance. Wise of them, I'd say.
I believe the duck on the left is the adult male domestic duck, and the other one is a Mexican Duck that took up residence with them. I'm not positive of the sex of either of these ducks. I suppose it's possible both domestic ducks are females and the Mexican Duck is a male. One of them is a male or the eggs wouldn't be fertile.
