That's interesting. I also had a friend with a feisty little D'Uccle rooster. Maybe it's common in the breed. My D'Uccle x Silkie was great though, not sure what breed he took afterThey red up pretty fast. Hens are womderful, however I have had issues with every D'uccle male I had once they hit sexual maturity. Hoping it was just the line inhale last time, but just a heads up
