Pros: Sweet, gentle, NOT aggressive, small, beautiful, and the list goes on and on!
Cons: NOTHING!
I have 5 D'uccles hens, and 3 cockerels of various colors. These birds are the best!! They fly onto the feed tray in the morning, eat out of my hand, the roosters are not aggressive AT ALL, and they come in many lovely colors. I really can't say enough good things about this breed!
