I can't really help because I am still new really to ducks. I own three call ducks. They are just over a year old. When we first got them they bickered and the two older (by two weeks) girls bullied the youngest for a good few weeks. Finally they settled and we didn't see any bullying again for a good year until about a month ago and now the bullying has started again. Although I have seen the littlest one attempting to assert herself so I think the other two are just showing her where she comes in the pecking order? The only difference pecking order (once it is established) seems to make is, if there is a cat, the alpha duck quacks at it and holds her ground while the other two run to the hut. (They have an electric fence and I work from home so I am on the scene or the cat gets zapped). Once the bickering stops there is no duck that gets extra treats or anything like that, they all share nicely. It is sad to see them bickering again though. I have to stop myself from interfering! I do interfere when it gets too mean tho... although when I say too mean, it's not too bad. No feathers get pulled out or anything. It's generally just a beak up the butt!
