My 14 month pair of runner ducks is terrified of the new ducklings and it's stressing them out. When I finally integrated the flock outside for the first time (they had previously been separated by a wire enclosure), the older ducks did do some of the initial biting and chasing, but now the tables have turned. My six week old ducks(2 runner and 1 Khaki Campbell) are now doing the chasing and biting and general harassing and my older ducks run away in fear every time the terrible 3 (the ducklings) make their appearance. There is one duck in particular, my Khaki Campbell, who is constantly biting the necks of the older ducks and charging at them, when my older ducks are minding their own business. Does anyone have any tips? Will everyone eventually mellow out? Should I be doing anything?
