Possesive duck

[Freie Family Farm]

Our female appleyard seems to be ultra possessive of ALL our males except one. She isn't a fan of our muscovy male. But she guards our 3 khakis and 1 saxony male under all circumstances. Including if they try to mate with one of the other females. We are getting rid of 2 of the khaki males soon. Im worried her behavior will continue and that she may try to harm future ducklings. I don't want to get rid of her but she's a bully. Always nipping at the other girls and our muscovy trio even though they don't hang out with that group. Shes also extremely loud and obnoxious. Is there a way to calm her down or should we find her a new home? I was hoping to keep her because she is our only appleyard and she was a fun story to tell others (ordered 5 muscovy: got 2 saxony, 1 appleyard and 2 muscovy of which one passed away 2 days later)
Any advice would be much appreciated

Her behavior may change when two of her drakes leave. There's really no one to make the decision but you. Good luck!
