Mille-fleur, French for " a Thousand flowers." when I have ordered from cackle hatchery or ideal poultry they are under cochen bantams, cochen is the feathers go down the legs also, adorable! cackle has 3 different breeds of mille fleur bantams,....we have kept up to 12 chickens in a 7x7x4 foot chain link dog cage. we cover it with tarps partially and move it to new grass every other day....that way they aren't living in their poop field! when they are fully grown, usually 6 months, we'll put them in with all the others in an electric fenced area that has a chicken barn, roosts inside. we also keep a couple of the same chain link cages, open doored , inside the fenced area and they regularly go into them, probably because they are familiar....have fun and let us know how it goes, star in texas at chickenscratch farm
