The thing with mille fleurs is that unlike whites or blacks the color can change alot with age. Some have alot of white when they are young, and some don't get their full coloring until after a few molts. For example I have one mille fleur at 7 weeks who already has a nice amount of white, so he'll probably show better as a cockerel but not as a rooster because he'll probably have too much white by then, while at the same time i have two other 7 week old mille fleurs who do not have close to any white/black dotting yet and will probably show as hens better than pullets because they seem to be slower developing birds color-wise.
