I think she looks more like a Swedish Flower Hen. I am not seeing the long legs, the long back or the large folded over comb of a leghorn and that is not a leghorn tail either. The Mille Fleurs are an eye catcher though. My brother got into Swedish Flower Hens a few year ago because he liked the color. They failed to thrive on his farm in Maryland while his Buff Orpingtons were kicking butt so he sourced a breeding quad of Jubilee Orpington to make the switch. The last Mille Fleur I have was a Champagne Mille Fleur Basque Hen. She was taken by a predator but below is Poppy Seed.
This is Poppy Seed on the right, Gloria and the Left and Doc in the middle back. :-)
