OK folks sooo I have a duck that is nice to me. But when it comes to here being nice to my 6 week old mallards she acts like demon spawn. She will bite there wings and pull feathers out. I dont know if she is aggressive or just mad cause she is laying eggs. Any advice is welcome.
Try to separate her from the mallards until they are more mature. Bigger ducks pick on smaller ducks. It's the pecking order, and sometimes it can get out of control with drastic results.
Definitely separate them! Although I do have some ducks (only the drakes) who do the same thing to adult ducks, especially when it's time for snacks or regular feedings.
