This is an amazing thread. I think I'm finally starting to see the differences!
Unfortunately, I think Phoebe needs a name change. I'll post a picture later; I can't find a camera anywhere. "She" has changes so much in the last week those pictures could be of a different chicken. She's a beautiful black/white; she's very flashy (I should have known then). About a week ago (7 weeks old) her comb turned bright red and has three distinct bumps on her comb. She also has thick legs. Thank goodness no crowing yet.
You could change her name to Phoenix.
