If you get it at a feed store, TSC, whatever - GUARANTEED it is an EE, not an APA Ameraucana. VERY FEW hatcheries sell APA Ameraucana. If they do, they will be sold as a SPECIFIC color. NO big hatchery, to my knowledge, sells APA Araucanas.
Many of the big hatcheries sell EEs under the name Ameraucana, Araucana (both are APA breeds and look totally different) or Americana (in an effort to mislead given the spelling is so close). There are some honest big hatcheries that sell these birds as Easter Eggers. It isn't a breed, you have no idea what color and pattern they will have when they are adults.
EEs are great birds, I have 4.
Our feed store even spells it Ameraucana! Which makes me mad!!!! They where easter eggers! One year they called them Araucanas and was telling everyone they where tailless! Charged a pretty penny! I told a girl that had some in a box! They look like they have tails! She just looked at me funny! I bought a couple to grow out and see what they where. They where 100% good old easter eggers!
