I have 5 male and 1 female domestic mallard ducks. Along with 16 chickens and 3 geese. The geese are female and the ducks are very aggressive towards them. The male ducks are always on something (female duck or one of the geese). The geese are scared to death of the ducks. Do I get rid of some males? Do I get more females? I'm not sure what to do with these guys. Any suggestions? They all free range on our 35 acres and come into a pen at night. They share the same pen. Is that the trouble? Lol this is as difficult as raising my three boys.
