putting adult ducks together

[dandar]

I have a pair of blue/black swedish ducks, i went to the swap meet and got a beautiful buff colored Khaki duck..he is awesome (i say HE ) cuz i was told he was a male...okay, now I get him home put him my "isolation" cage and they have "f2f" contact..I did let them out (per free advice) and was told that the males would have to get a pecking order..but i only let them together about an hour, cuz my male swedish just would not leave the buff alone..so i went out this am and in the pen with my rooster and the buff khaki...i found an egg!!!! i no it didn't come from my rooster....SO NOW I HAVE A FEMALE KHAKI....
after the experience that my male swedish and buff yesterday. I am wondering when and how I should join these 2....btw the female swedish, pays no mind to the buff. I am going to continue (for safety /health check reasons) will keep the buff Khaki seperated for a while yet.
I am a fime believer in "adjusting periods"
but what i don't understand is WHY my drake had it out for her, and yet not the female....do i need to get a male buff (which was my intention) anyway...is it the pecking order, or will this male swedish kill the buff????
thanks

Territory? Probably not sure about a new strange duck showing up in his territory all of a sudden. If you can separate them, but let them see each other, after a month or so you could try introducing them again.

Sometime they just pick one to go after. When I introducted 2 new flock members my girls got along very quickly with the female but would not leave my new male alone. It took about a week or two before they started to let up enough I was comfortable locking everyone in a at night together. Now he has finally put the girls in their place and he is the man around here. I've had for about a month and a half now. A fence where they can see each other for a few days would be good and then take it slowly from there.

i have been letting them all together about an hour a day SUPERVISED and the male just chases the new FEMALE buff and won't let her near the pond or anything however they do try to have a 3 some when he gets a hold of her

..seems like the female swedish seems like she is trying to teach the buff ??? would it help if i got more females about this age OR what will happen if i get more...i keep the buff seperated with my rooster buff orphington who is tearing the girls backs up ....planning to add more hens this spring ( i hope) i have about 3-4 acres all fenced so let the ducks and chickens forage together, and works well..I have been housing everyone together at night and seem to get along at night.
