Hand raised Egyptian Goose female mating with wild male

[marios5]

I raised a female Egyptian Goose from a chick and she recently laid 9 unfertilized eggs. Ever since I took the eggs out of the nest, here is a male chasing her and then she chases him away again. I can't figure out what the male's plan is and whether he might want her as a partner? My female keeps a distance from the wild male all the time. This is the first time that a male has stayed here alone for so long. There used to be many wild geese doing their rounds here, but then all of them are pairs.
What would you consider the behavior between the wild male and my tamed female to mean?

Is the male the same breed? I'd keep her in a covered run to protect her from aggression and diseases from him.

Hi yes, it's the same breed. They also lay or stand a couple of metres from each other for long times and just watching each other.
