I have 1 Brown Chinese goose, 1 White Chinese goose, and 10 ducks. They are all 20 weeks old. Ever since they were 10 weeks old they were around my other 6 ducks who are all between 1 and 3 years old. Now that they all free range together the ducks get along great, but the geese are a different story. Every time the older ducks get within reach of the geese they grab on to their wings and thrash them around. I tried to put them in the night pen together for the first time last night, and the geese had the 6 ducks pinned in the corner, and they were biting them. They are around each other all day, so why don't they just get along? What can I do to get them to like the ducks? I was going to get more geese next year, but now I am worried about my ducks getting bullied. Thanks for any suggestions!
