There are a ton of Cochins around the country now that are out of Mille Fleur projects. Problem is, MF's are still a project, and no one has yet to breed them true. So any other project that has MF in it will also not breed true.
There are only one or two CLOSED Mille Fleur project flocks in the country, to my knowledge. They are the only breeders that can tell you the exact genetic makeup of their birds, going back several generations.
