Does anyone know what to do with a gander attackin a goose?

[Happy Quack]

Has anyone had a issue with the ONLY gander attacking a goose? I have four geese and one gander. He hates my Chinese/production African what ever she is goose. He has attacked her and will not let her near the other geese. I have to keep her in a crate at night to keep her safe. Any suggestions please.

The goose he does not like has been vent sexed and is a female.

If not raised together , she is not of his flock... Separate them in adjacent pens and give her a 'friend' from the other flock... Eventually, you may be able to add them together... Or if the birds were only raised with the same type can be "prejudiced". During breeding season things can get hyped up... (Sometimes vent sexing can be in error)
