We got 3 new ducks yesterday. They seem very healthy and they really wanted to be by our ducks so we put them all together today (I know, shame on me for skipping quarantine!) and they did pretty good for the most part. But our new pekin, who is by far our biggest, seems to be a bit of a bully. She was running at and banging her chest into some of the chickens and my ducks and trying to bite them. She wasn't that bad and only acted like that for a little while, the rest of the day everyone seemed to get along fine. Though the 3 newbies kept to themselves and my current birds hung around as usual. Will the pekin keep attacking as a way to assert dominance or was that more likely out of fear since she's in a new place with more animals? The new ducks used to just sleep outside but tonight they surprisingly went in the coop with everyone else at sundown and they all seemed to be getting along fine. ETA: My ducks and chickens are sissies and didn't fight back, but ran from the pekin.
