I really like the look of a milie fleur but there bantams. Other than a russian orloff or speckled susdex. What else is similar? Is the sebright similar pattern?
You listed the two breeds that would be closest already. Jubilee Orpingtons too. I love my Mille Fleur D'uccles. Seabright is not similar and they have a different personality type.
Swedish flower hen. Not "exactly" the same. But very similar. Unfortunately they are a landrace so don't breed true. (Not ALL of them have that coloring.)
