That's a nice variety! I have always wanted Silkies. My girls that I currently have aren't so nice to small chickens, so I can't have any bantams. I'd love to have some Silkies and d'Uccles some day. What color Silkies do you currently have?
You should get all bantams instead! I love my bantams and my standards, but bantams always appealed more to me. When I have my own farm, I'm not going to have any standard hens. Don't get me wrong though, I love my Polish and my Orpington!
