So since the website I have been using for research is obviously wrong, CAN roosters mate ducks? And CAN chickens (rooster as well) and ducks live together? I am NOT getting a drake.
So far, this forum has had mixed opinions on your question. But the vast majority of responders say that you CAN have both ducks and chickens living together. Especially with no drakes, the answer seems clear. Go for it.
Thanks! My rooster does tend to be aggressive, but a real gentleman with the hens. Does that pose a problem? Would he attack the ducks because they're not hens?
