Aggresive Pekin Ducks

[summer9498]

We have a mixed flock.
- 2 Adult Pekins (1 male/1 female) female is 18 months old and the male maybe 2-3 years
- 2 Pekin Ducklings (not sure yet on gender) 8 weeks old
- 2 Khaki Campbells (believe 1 male/1 female) 8 weeks old
-6 hens and 1 rooster all 8 weeks old

We have a large indoor coop area where my one adult Pekin has her nest in the corner. We also have a large covered run approx 144 sq feet. My birds have access to 2 ponds and unlimited free range during the day.

We integrated the chicks and ducklings into the coop about 3 weeks ago and everything was fine for about a week. They were only together at night. Our adults were let out to free range during the day and the babies were cooped.
The coop door accidently got opened one afternoon and a friend closed it for me (cooping all the birds in together). During that time my adult Pekins attacked my Khaki Campbell ducklings.
At that point we segregated the adults from the babies at night to try to prevent it from reoccuring. However I am still having a problem during the day. Now when I am home I will let them all out to free range and see to it that my adults will go to be on the pond. However, at points in the day they will return to the coop and only show aggresion towards the Khaki Campbell ducklings.
I am not emotionally attached to the adults due to the fact that they wont come within 30 feet of anyone.
At this point I am considering getting rid of them. I am not sure which is the aggressor. I am wondering if I get rid of him if she will be less aggresive? Or if I work hard to keep them seperated and wait until the ducklings are larger, if they wont be able to defend themselves? The Campbells are so sweet and passive. I also don't understand why they are only attacking the Campbells. They do seems to be wanting to attack the female more, but not in a mating sense-more territorial.
Any tips would be GREATLY appreciated!

Some have told me that in certain groups. ducks seem to show a prejudice against those of another breed. That may be what is happening here, and if you can rehome the Pekins without it being a hardship on you, that may be the way to go.

Good to keep the littles safe.

Thank you. I had never heard that in my research! Everything I read before we got the original Pekins pointed to go with that breed, but my khakis are MUCH more personable.

Yes, I recently came across the possibility of breed prejudice when one of two adopted buffs became picked-on by my runners after her b.f.f. died. I got three more buffs, and it's been tricky - partly due to one of the buffs being a drake - but I think part of it is breed difference. Things are slowly working themselves out, but the ducks are all about the same size.
