I have 2 ducks, a Rouen and a Black Swedish. The Rouen is male and the Black Swedish is unknown (I assumed male). I noticed the Rouen was mounting the Black Swedish today. I know it is spring but would the ducks (lets assume they are both male) "mate". They are still in their coop as our pond is still iced over and we cannot let them out yet. I have never seen any evidence of eggs (they are 11 months old). Any experience with this? Insight? Thanks!
