So i have 4 week old ducklings and 2 week old goslings. One of my gosling started pulling at the back feathers at one of my ducklings so now the back is completely bald. I separated them and all seems fine but when I take them outside to go swimming and to play around in the yard for the day that same gosling attacks that same duckling. It got to a point where another duckling I am believing male started putting that gosling in it's place but took a chunk of feathering from the gosling with it. What are your guys thoughts. I plan on doing more super vision with this since they all need their exercise and swim time but I don't want to segregate them forever. Any advice? Also I have no idea what breed they are i am thinking buff geese.
