Trying to figure out if these are EE or Amercauna. Also would like to sex them. This is Blanche (?) supposedly a Leghorn. Concerned because I see the curve in the tail feathers and most of the pics I have seen show pullets with straight tail feathers. This is Chicken Fries. Bottom of feet are not white so I'm assuming EE. This is Sophia. Please tell me she's a she! Bottom of feet are white.
