My Millie roo took 5 weeks to start getting his flowers. Seems he had a little more black on him, though. The big chunky feathers on the feet were the only give-away ... what do the feet look like?
I'm pretty sure you have a chicken, just not sure what breed. The bantam doesn't look like my Mille Fleur D'Uccle, but there are several varieties. Mine didn't get his "flowers" until 4 weeks or so. He was just orange with lots of feathers on his feet.
Welcome!
