Hello, all! Quick question. I have 2 ducks, about 4 months old, a male and a female. The male keeps pinning down the female by her neck. I took this as bullying and separated them, because I read somewhere that they're not sexually active until they're 1 years old, and any behavior like this outside of mating, is bullying. Am I right to separate them, or are my ducks really just trying to mate?
