My 14 1/2 week old rooster, has decided that he will mate my Female Duck on a daily basis!! Why would he choose the duck?? This has been going on for 2-3 weeks now!! Not that the duck seems to mind, but geesh!! will he ever figure life out??? Hubby finds it amusing, and wishes we could hatch some Duckens!! Too bad it cant happen!! The other roosters the same age, have figured out that the hens are the way to go.
