My calls have summoned in a breeding pair of pacific black ducks. My calls don't seem to mind having the wild ducks around and the wild ducks are staying separate from the flock I expect they'll nest with us as they have been here a week now and once their young get eaten by the local cats take off unless I can drop a chicken tractor over the female while she's nesting to protect them, still it might drive her bonkers. Anyone want to weigh in on if I should attempt to protect the wild duck/ducklings the way I would my call mums and bubs or not?
I'm with @Julie Bird . It would be very hard for me to resist doing something to protect them simply because I love ducks, but the ducks themselves might not appreciate your efforts. I guess you'd just have to try it and see.
I have to admit that the thought of wild ducks around my Calls would freak me out a bit because of the Avian flu outbreaks in the US again this year, but not sure if that has affected Australia.
