What does LF stand for? I assume it means "regular sized duck" but I can't figure out what the actual term could be?
We have a mixed flock, BUT the fullsize ducks are both female and the bantam is a boy.
We also have one of each gender that were supposed to be bantam, but a cayuga/swede drake apparently ran with the flock, too, so they're a little bigger. Still smaller than the welsh harlequins (or Pekins) that I'm familiar with.
With our particular flock mix, I figured we'd be fine, and after a year, I still don't think there are any real safety concerns. But even so, the Pekin was being seriously plucked by the half-bantam drake because the size difference is enough that if she's not interested, she can keep him from successfully mating with her. And never satisfied, he just keeps trying. We took in a second Pekin who happily DOES enjoy the process, so now everyone is much happier.
Well, everyone except our bantam boy who STILL isn't allowed to go near any of the ladies. Sure hope the two new ones are girls! (I tried to vent sex them before choosing which ones to keep, but I really don't know what I'm doing!)
