Favorelles are a French breed of chicken with single combs, beards/muffs, feathered legs, and five toes on each foot. They lay brown eggs. The bird in the picture has a pea comb and blue in the hackle feathers, which makes me think she is an Easter Egger (often sold as "Americanas" or ameraucanas by feed stores/hatcheries). I do like the paler blue/buff color combination for Easter Eggers though, very pretty. She'll probably lay green eggs, although she may lay pinkish-brown, cream, or blue eggs. Part of the fun of Easter Eggers is that you just never know what exactly you're going to get as far as feather colors or egg color.
Like said, many people mistake birds like her as "Americanas" or Ameraucanas or even "Americaunas" but it's just false advertising/selling/informing from the hatchery spreading down the line. Easter Eggers lay colored eggs (blue, green) like purebred Ameraucanas but unlike them, they're quite common and come in a large variety of colors and backgrounds.
