isnt easter egger and americana the same bird?
Yes--if you're spelling it AmerIcana--which is a misspelling of AmerAUcana. Ameraucanas are a breed of bird with a Standard of Perfection. Easter Eggers are any chicken that carries the blue egg gene and doesn't meet the standard for a breed. Any time you see birds advertised as Americanas, or Ameraucana/Araucana, or even Ameraucana without a color attached (like Blue Ameraucanas) then you are most likely buying Easter Eggers. You can only get Ameraucanas through breeders or a couple of hatcheries (Meyer and My Pet Chicken), and they will always tell you what color you are buying. If they say the bird lays green eggs, it's an Easter Egger. If they don't tell you the color of the bird, or say they'll all look different, it's an Easter Egger.
