I am new to raising ducks. I had a female Pekin wander onto our property about seven months ago. Because she was our one and only, I picked up two ducks at the hardware store, not knowing what sex or breed they were. As the months passed, I now have two adult males, a Welsh Harlequin and a Cayuga, and the female Pekin. They are what we call The Three Amigos. I found Backyard Chicken while searching for duck behaviors. My two males are making honking-whistle sounds. I figured that it is some type of mating ritual, but I'm not sure. I seriously thought that they were imitating our neighbor's mule. I am a retired engineer who is too busy taking care of our property to even think about a hobby. I suppose that my hobby is just keeping things together: Property, house remodelling, cars, trailer, animals, etc. You know, the "stuff" of life. My wife is an author and my kids and grandkids are in Kansas.
