My ducks (5 runner, 2 swedish, 1 cayuga) are 1 week shy of being 5 months of age. No eggs yet, although I take a sec to peek into their hut in the mornings to be sure. This morning, while I was taking my sweet time, they all hopped out and started splashing in the pond like they always do - and then I realized that one of the black runners was mounted on the F&W and they were doing the ducky thing (eg, trying to drown her for a few with tails slashed over to the side). #@%@#%@% - so now I have what appears to be a black runner drake in my flock of laying birds. There is no sign of drake feathers and no inclination that this duck was different than the others until now. I have also noticed another odd behavior.. my largest duck, one of the Black Swedish, is always being dominated by one of the black runners (not sure which one, hard to tell them apart) - neck is over the swedish's back, making staccato noises. Never anything more drastic, but it keeps the swedish in the background at feeding times. Question: Is that a behavior that one male shows to another at the bottom of the pecking order? I would hate to have more than 1 male (I don't want any!) that I have to re-home. I will try to film them sometime soon.
