If I didn't see it I wouldn't believe it! I have 3 female, five month old American Buff ducks that have been exhibiting mating rituals. I witnessed one on the bottom, flattened out with one above holding it neck sown under water, with the third duck on top of the second duck. Three ducks on top of each other in a row, supposedly female... Is this typical behavior? There is so much mating like behavior going on throughout the day that I am questioning the sex of the ducks.
